with the track changes on the bottom of the seats they should be a direct bolt in. i know u can do 1st and 3rd gen seat swaps. i havent seen a 2nd gen bolt pattern in a while. they all may be interchangable.
I also found that out when I went to the junkyard to try. Sadly the seat from a 3rd gen 2.0L LX didn't fit in a 2nd Gen 96 LX. At least I tried. What a sad sad day for me.
Oddly enough it looked like the 626 seat was similar to the 3rd gens. I saw one overturned and the look similar. Didn't bother trying to see if it fit into the 3rd gen.
ive got a set of P5 seats for sale, or i sell several styles of racing seats and i have some more seats that i can order, just havent put on my site yet.
