Have a chance to pick up a 69 GTO failed project. I am just wondering what body parts and interior on the 69 will interchange with my 68. Bumper,fenders,seats. quarters,hood, trunks and any other parts you can think of

Bumper: except for emblem holes are the same (I am referring to the Endura)
Fenders: Same
Hood: essentially the same (minor diiferences in crush-zone construction and holes for windshield washer nozzles, etc but will interchange as far as fit.)
Seats: will bolt in , upholstery is different (seat releases may be diiferent location, don't know for sure)
Trunk: will not interchange
quarters: rear running light location is different, but can be made to work
Dasboards and steering columns are different ( ignition key location being one reason.)

ALL STAINLESS.

Bucket seats are shaped differently, but will bolt in. That means you can't upholster 69 buckets with 68 covers.
Doors on the 69 did not have the vent windows, so that may make all internal door parts different also.

I put a 69 pattern on 68 buckets with excellent results. Just don't remember making any clarity about 68/69 bucket differences when ordering. I assumes the buckets and backs were the same. Ignorance was bliss.

for some reason, it seems that 69 used parts are easier to find than 68
