I'm sure it's here somewhere, can someone lead me in the right direction on ways to add disc brakes and 8 lug shafts? Is it easier to do the 35 spline convert or weld up and re stud the outer shaft and back shaft. I just got a 67 M715 on 5/1, I'm tearing it down, came with a chevy 292, unfinished from '87, old owner wanted to put 292 and chevy toploader, think I want to kill the old rust and get it driveable, no resto, just a fun truck, thanks for any help
