A couple options that I'm looking at are...Recaros from a 79-82 fox body, with after market/Recaro seat rails. Other cars like 79-80 T/A's has Recaro option as many German cars from the 70's into the 80's

my favorite seats to use for bucket swaps are the cloth ones from the generals men.  Smacked up cobalt or whatever.     cheap and plentiful.   anything fox body, sn95 or even s197 will be close on the width of the holes left to right though.    unbolt the factory tracks on the pinto seats run a couple strips of 1/8th by 3/4 bar across the bolt holes of your new ones and locate them as you want em if required.  drill some holes to tie the two together n bobs yer uncle.  most of the height difference is in the fact the pinto seats are tall at the cushion but most new stuff isn't as thick (you sit in em not on em)

so basically what wittsend said.  BTW I like the turbocoupe gut swap.

I saw that fix in Hot Rod when Pintos were new. Still works ok. Take all 4 bumpers out if you want to play "low rider".
