It just occurred to me that this may have never been posted before by myself, or my brother, so I'm doing it on his behalf.
My brother has a 1974 GTO, and he cannot find a good rear hatch.
I believe that he has a spare, but it is nearly as rusty as the original one for his car.
If anyone has a lead on a good hatch, please shoot me, or him a PM.
My brother is

Now, I would guess that this might be a 1968-1974 GM X-body part, but I have very little knowledge on 1974 GTO's regarding parts interchange.
Thanks!!
