Sometimes things just do not work. I am installing the interior in my 1967 and before installing the side rail carpet, I thought it would be a good idea to test fit the seats and tighten down the rail supports.

Neither the passenger nor the driver seat seats would fit on the rails. The width of the seat rail is between 18.75 and 18.82 inches. The rails need to be 19.25 inches for the seat to fit the rails.

I bought the car in pieces and the neither of the rail support pieces were original to the car. The rails have not been replaced as they still have trim screw holes. My looking at the parts manual, it appears that there was only one version of the rail support. Did the 912 use a different a different seat support?

Anyone else experience this issue?
