I picked up a pair of seats from a friend yesterday. We have no idea what they came out of. The best I can tell, the seats have not been recovered and are in their original factory condition. If I can identify what they fit, I may be able to buy factory type covers and save some bucks.
aftermarket...I put a pair just lime them in a Beetle I built once. Check around in some car mags, and maybe JC Witney ( I Know theyre junky sometimes, but I think you'll find everything there) to see if you can find seat rails and it should bolt right up......
Could be out of any german caraudi ,BMW,probally VW rabbit from the covering,They are comfortable,I have a set in my s-10.If you weld you some brackets and move them a little closer to the doors you can mount a 85/86 camaro console in there .
