Working on buttoning up my 2 speed to c4 swap in my 64 and have a question concerning the slip yoke depth into the rear of the transmission. I’m using the stock length driveshaft from the 2 speed and not sure if it’s long enough based on the yoke depth at the rear of the transmission. Looks like it should be in further. Does this swap normally require the driveshaft to be lengthened? The pic was taken with the weight of the car compressing the rear springs.
