yeah, i spoke with a vendor about them this morning at a swap meet and pretty much confirmed my thinking as to the problem. when they changed the rears in 74, the last part of the quarter where it goes to the tail panel is infact a different length than the previous years. the angle where it welds to the tail panel is also different slightly. AMD did not stamp these panels for much more than a year from what this vendor told me so she thought as I did, being that AMD realized their issues and stopped production of them.
