Currently working on the rear for my 38 coupe. I would like to replace the solid driveshaft with one in better condition. It is the one with 6 splines on both ends. The read end splines are worn and the coupling pin was broken when I disassembled it. I found one with decent splines but the center bearing surface was worm. These things seem to be harder to find then hen's teeth. Does anyone know a source? Thanks.
