How long is the drive shaft in a 72 convertible? Is the yoke a 31 spline for a FMX transmission? I took my driveshaft and yoke to a shop locally to be balanced and now they are playing games. I think they will try and give me a different one and I would like to keep my original one because that is what came on the car.

Driveshaft varied with engine and transmission. The 351C FMX cars had a shorter driveshaft than the 302 FMX due to the difference between a 9" and 8" axle. Dimensions in chart below are center to center of the u-joints.

The FMX has a 31 spline output.
