Basically ive found a subframe to fit my OMP seats into my Defender but emailed the shop and they state is fitted for a 1985 - 1990 Defender is there any difference between a 2002 Defender?
I can't confirm sorry, but I don't believe the seat box in Defenders changed greatly until the very latest generation. I can't be sure about the exact position of the bolt holes though.
my 90 is an 1985, it has 8 bolts to hold each seat, i replaced the seats for some from an unknown year and they had only 4 bolts but lined up perfectly with 4 of the holes
