My next build I’m going all out and making it as lite as possible. Starting with a 7 1/4 rearend and upgrading it with unobtainium 4 bolt 3/8 aluminum stud axles. I’m going to flycut the ring and pinion thinkness and make up the thickness difference with Old Milwaukee beer cans. I’m going to save more weight and drag by leaving the rear cover off so I can spray the ring and pinion down with Pam cooking spray before each pass. Looking for some new bests in 2019
