I recently purchased pull cups (C9Z's) for my 69 Mach and when I went to put them in, 2" too small. It was suggested to me that perhaps I have the wrong door panels on (70) and that that the pull cups were longer in 70. Is this true? or is there a difference in the 69 pull cups (deluxe int.). I purchased the door panels from a well respected catalogue, could they have sent the wrong thing, do they look the same other than handle size? Any help would be appreciated.
