The rear flex disc on my '80 SD is shot. The rubber is all crakced and coming apart, hey what do expect for a 22 year old piece of rubber. So I bought a new one, now for the replacement. Is it as simple as unbolting it from the drive shaft, or is it more involved than that? I was informed by one of my indy's mechanics that once that disk lets go, I'll be on the side of the road with my driveshaft lying on the ground.
