i see no reason why they wouldnt bolt right in
toyota didnt change stuff, just because they could
if you follow that train of thought, then everything from a first gen will bolt up directly into a 3rd gen.
I have 95 4runner seats in my 2nd gen, and yes I had to mod the rails a bit to get them in. When I had my 79, I had to drill new holes to bolt in buckets.
