1972 Dodge Colt

Those RAS Rocker shafts can be thin/ soft - Don't tighten them too much as they will squash out and bind. I used less torque and some red loctite on the RAS unit I have n my '69 Dart. They have worked fine since ~2006. and ~30,000 Miles.
I never had any problems with the shafts. The torque is pretty low if I remember. Like 35 lbs/ft?
