I would like to find a shop manual for the truck in the title. I have rebuilt the engine and added a RV cam, Edelbrock manifold, Speed Demon Carb, Headers, dual exhaust with a cross over pipe, MSD distributor, and a Digital 6A Multiple Spark Discharge with the matching coil. Now, I need to turn my attention to some drive line issues. I would like to know how to replace the rear brakes and rebuild the entire system as well as add a Lock-Right to the 14 bolt differential but can't seem to find any helpful information. All the books I have seen omit the C30 --- Can any one help?
