Chuck, as far as front seats, keep your eye out on craigslist and the classified ads here. They will come up occasionally. I’d also suggest posting in the cortez yahoo group to see if anyone has a set lying around.
I have a complete 1968 Cortez, EXcellent Industrial Slant 6. Has a bad Master cyl. I drove it where it is, Under 5k on rebuilt transaxle and has a BRAND NEW Starter rebuilt professionally. Clean title and currently Licensed in Iowa. Not a rust bucket, has had some fiberglass work but it was poorly by my Bro-in-law (bought it from him) since bought something bigger Great parts or this complete restoration pridject. saw the body before and only has a little rust in a couple spots.
Decent body and it is complete! $1400.00
