I believe you will find the ebrake drum is nothing more than a 2" x 12" GM 6 lug brake drum, I've had owned 4 C50's, one '60, a '67, a '71 and a '72 all had similar transmission mounted ebrakes. Don't bother looking for the ebrake cable, they are long out of production, I sold the last one I had to a gentleman in Indiana, IIRC, only to find out I needed one about two months later. Finally endup with one from a military surplus oufit, it is too long and had to be adapted on one end. Now installing a Spicer 3053A out of an M35A2 with no provision for a trans mounted ebrake,,,, back to the drawing board!
