That would make sense because the stud is roughly an inch away from the dimple giving more clearance for a converter. The guy I bought them from said they were out of a 73 Scamp, I have no way to prove that right or wrong. I figured they were out of a Duster, because the pattern of the covers match a 73-74 Duster seat, and I have never seen a Scamp with factory bucket seats so I assumed that was kind of like finding the holy grail of Scamps.
Thank you slopar72, for the info on the conversion you have done. I've got the measurements for the console off a post on here. I just was not sure about buying the 727 floor shift parts for mine, because I was not sure they would work for a 904 but sound to me like that are interchangeable.
