Hi I've just recently bought a 1972 chevy C50 dump truck. Driving it home the emergency brake seizes up and both driveshafts blow out the bottom. The drum for the e-brake is destroyed along with the rear driveshaft. There's a 16 spline as well that was damaged. I'm trying to find lengths of rear driveshaft, what drum they used on the e-brake and the 16 spline, female side, any info will help thanks
