braink: much has been discussed on this issue. A search may turn up a lot of reading!
It depends on what your looking for. Originality or functionality.
Most folks say they are using a seat from a silverado, some say a seat from say a 2004 Buick LaSabre, some say a second or third row from a surburban....even an explorer.
The main reason if for the built in seat belts.... heated seats, power adjustment and so forth.

Take your tape measure with you to a junk yard and see what you find. That is what I plan to do for my panel. May get lucky and even find a matching color!!

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
