  • Swapping Defender front seats in to an 88"

    So, I have a 110 in the backyard that is a "someday" project. I recently sat in the front seat and it was more comfy than the Series 3 deluxe ones. No big surprise there. The 110 seats appear to be "modern", while the Series ones look age appropriate.

    I did a few measurements and found that, yes, I can swap seats. The bolt patterns are good to go, at least for what I'm doing.

    I've got the driver's seat swapped into the S3, using the original Series fasteners. The Series seats use 2 bolts (flathead screws, actually) on each corner, compared to 1 bolt on each corner in the 110. The Defender seats use a different hole for its fasteners, which lives in between the two Series holes that are also in the Defender seat frame. To put the Series seats in the 110 (which I'm not planning on), I'd have to drill the 110 seat box to accept the two-per-corner fasteners. Photo below shows this pretty clearly.

    After a week of driving around with a "new" seat under me, I have some observations:

    They are nicer seats, even though this one is probably from the 80's (older than my S3 seats are), and has had critters living in it (past tense, I hope).
    It's a bit better at insulating my backside from higher frequency vibrations, probably because of better padding. So, a bit less fatiguing over a longer trip.
    The seat is a bit bigger. It overhangs the seat box on the front (at least with my current adjustment). The front adjustment bar is father over the seat box. It's taller, because it has a head rest. The bolsters ("squibs" in UK speak?) have more shape.
    Adjustment is limited because of the Series truck's tub bulkhead being right behind the seat. With the original Series seat, there's a bit more room for taller drivers. You can adjust the seat back angle on the 110 seats, but that's negated by the relative lack of seat travel in the rearward direction.
    For me, at 5'8" and relatively thin, it works. I'm trading legroom on the order of maybe one or two clicks of adjustment (about one inch/2.5cm) for greater comfort. So far, the trade offs look good.
    If I was much taller, I might not like this new set up.
    The headrest is pretty far back. I think that's because of how it has to be adjusted for me. I need to move my head uncomfortably backward to hit it, but even so, it should protect me better than S3 seats if I get rear ended. My boys like to climb into their back seat through the front doors and over the front seats. The head rest may get in the way a bit.

    I can imagine this being a great set up for a 109 5 door, without the seat back bulkhead (assuming that long wheel base 5 doors don't have that bulkhead - corrections welcome). I know a lot of Series owners upgrade to Defender seats, and now I know why. New Defender seats are out of my budget, but I luckily had these old crusty ones to experiment with.

    It looks like the seat has been recovered or reupholstered at some point. I'm noticing the lack of stripes in the center of the seat back, but I don't have enough info on this.

    I'm going to see if Santa can deliver a reupholstery kit for the two outside seats. I'm seeing decent material choices from Exmoor at Rovers North, but I'm open to other suggestions if you have any. It looks like I can reupholster both outside fronts for half the cost of an entry level new Exmoor seat. The middle seat looks fine. The seat bases need paint, but are complete and they work. I'll probably spring for the seat heater kit that RN carries, but not the lumbar kit.

    Here's both seats for comparison. Never mind the torn vinyl - that just made it easier to clean out the mouse nests.

      Nice write up! I found my Defender seats on Craigslist. They went into my 3 door 109. I had to put spacers(1/4' SS washers) under the runners to keep the adjuster bar from scraping the seatbase. Because it is a 3 door it has a bulkhead behind the seats and these had seat back standoffs which were removed to allow sliding the seats back. I've been mulling the idea of making some canvas seat bottom covers.

        If you like the Defender seats now, you'll love them after you fit them with new foams and covers from Exmoor. I would recommend checking UK suppliers for those as the exchange rate is really good right now. Also consider adding Waeco seat heaters as part of the project.

          An excellent upgrade for a driver. Really make a difference on longer road trips.

            I think I forgot to check for seat back bumpers on the bulkhead, but really I think those fell off before I got the truck. I'll check soon, cuz it might find me that inch I need for legroom. Canvas covers are a good idea. I might need a better sewing machine though. Otherwise I'll be hand stitching for a while. I love my Speedy Stitcher, but still, that's a lot of work.

            Seat heaters for sure! Otherwise my wife won't ride along in the winter.

            After a week of driving with them, they are next-level comfy and they still need more legroom. As I said above, I'll look for obstructions. The seat structure itself has little opportunity for trimming, since the steel frame is at the extreme rear of the thing.

            I'll check UK sellers and see what that does for me.

            My issue with the seat back is this: the foam is too thick right under my shoulder blades, which pushed me forward. It's like a lumbar support option was installed too high. The result is that I need to rake the seat back pretty far to have it work for me. It's possible that mice have made some kind of nest in there that has inflated the size of the padding, but I haven't checked yet. I'm hoping that the foam/cover re-trim kit will have foam that is better contoured for me. I'm not an unusual shape, or anything, but I think the seat is. When I lean my head back to see where the head rest is, I'm looking at the roof. If a kit corrects that, I may be able to rake the seat back forward, which will allow me to slide the seat baser back an inch or so. Then, with luck, seating nirvana.

              Also, I should have paid more attention to how well the seats work before I took them out of the 110. I was in a rush to get them out. I think I recall that they fit pretty well for me, but can't recall about the headrest. The 110 has no bulkhead behind the seats, so they were able to move back farther, and that might have been enough.

                Awesome!

                Real quick: these are early 90/110 seats. There are a total of 8 mounting bolt holes vs the later 4. So If you ever do decide to get rid of these seats, try to retain the tracks.

                I got a set of defender seats out of a 1997 110. They were great. Then I got a line of a pair of new take out Puma seats. I'll tell ya'll right now, that is...THE TICKET. Last winter I finally setup the heated seats...its extremely nice.

                Great modification!

                  LR Max, I'll keep these seats even if I get other ones for the 88. The 110 needs them back at some point. My 110 is a 1987, so it's not even a Defender, yet.

                  How often do Puma takes out seats come up for sale, and where do I even look? D-source? NAS-ROW?

                    I had the same padding issue with my seats, the lumbar support pushed my lower back out enough the seat back was "even".

                    All I have is a Speedy Stitcher too......

                      Gene, I may have to modify the foam till I can get a reupholstery kit. it's not like I'm going to reduce its value or anything. Rasps and sand paper!

                      Post up your custom canvas seat covers when you do them. I'm sure it'll teach and inspire many of us to try it out.

                        I am trying to figure out how to do them, whether I want seamed or not. On one hand non-seamed would resist tearing and probably be easier to make and the other some sort of baseball stitch would look kool!

                          You could kind of make a drawstring bag sort of thing, with the string along the bottom edge of either bottom cushion or seat back, for instance, which wouldn't require much seaming. It might look as bad as I'm making it sound, though.

                          I'm trying to imagine a seamless seat cover, and that's all I could think of.

                          I like baseball seams, too. I stitched a leather steering wheel cover onto a friend's car, and baseball stitch is the way to go with that.

                          Lot's of choices for seat covers. Can't wait to see which direction you go in.

                          When/if I reupholster mine, there is an Exmoor option that isn't vinyl or leather, but some sort of fabric. That might be a good choice for really hot or really cold days.

                            Electric carving knife works great on foam.
