After my grandpa past away he left me his 1971 Chevrolet C10 short bed step side three on the tree pick-up truck. I am not in a position where I can start fixing it up, but I don't know where to start. The engine runs but needs some work done to it, I also want to lower it even more than he had it, which will be slammed to the ground with an air ride system on it. I am looking for the right size tires to put on it since it will be slammed. I also know I need to C-notch the frame, and I would like to put all disc brakes on the truck. I know this is a lot of information. I am looking for a starting point and the right parts to make these changes that will not break the bank. Any help is appreciated.
