#1-What year 14 bolts would be a direct bolt in to an 82 k5 if any? I will probably keep stock springs, will the half ton ones work or should I use the heavier ones off the original truck? #2-My truck smokes blue out of one side (dual exhaust) almost all the time and the other side only on start up. Would that most likely be rings, valves, or what? Thanks a lot, I'll probably end up taking the motor out and freshening it up while I put in a new axle. Is there somewhere I can look for what to replace while the motor is disassembled?
