1968 fastback Wondering about Seats

[thunderbolt]

I believe the seats from 69-70's fit without problem and I think 71-73 can also be used without too much trouble. But if I was going to swap out the seats, I would look to get something like late model mustang seats and fabricate the mounting brackets. I'm just don't like the comfort level of these old seats. I don't know much about racing seats, but mustangs plus has some, as does summit. I am sure they will be glad to advise you.
