A buddy of mine found these parts in his basement and he doesn't know what kind of vehicle they are for, other than 99% of his parts are for older Chrysler products. Unfortunately, we couldn't find any part numbers on these things.

One part is obviously some sort of vinyl covered door trim piece (you can see a hole for the lock post), and the other is a tail panel that would run between a vehicle's tail lights. If we had to guess, we're thinking the door trim piece may be from a 80's M-body (Mirada/Cordoba) and the tail panel looks like it could be from a `67 Barracuda.

Any ideas?? Any suggestions or help is greatly appreciated. Thanks in advance, guys!

Yes, 67 Barracuda on the tail panel trim.
Other than 69 or newer (due to lock knob location) not much on the interior door panel top. Dont think they came like that on the M's. I know they didnt on the F's, which are essentially the same as the M. Could be J.

Thanks for your input, Jim! After a couple quick Google searches, I'd wager that you are correct on this part being for a J-body. In particular, for the Mirada. My buddy said that the part came in a bag that was dated 1981. And for that year, the J-body Mirada had the lock post hole in this unique position.
