Guys, I am just about ready to have my 1969 Eliminator Clone interior redone. The car had an XR-7 interior. I purchased the correct seat covers (ouch $$$$) and also found a used set of 1970 Mustang high back bucket seats. After some research I am finding out that the upper seat back is not the same (not talking about the latch) they say the 69 is not as thick??? Anyone have any info?
