Hello viper nation. Just picked up my first viper a few weeks ago. It's a 93 and I have a few questions I am looking for help on. 1. Going to change the ring and pinion this winter and I want to pick up a second rear diff. what years are compatible? 2. Next year I plan on playing with the engine. I am looking for a second set of heads and intake to have ported and polished. What years /gen will fit on a 93. I will change the stock head gaskets, rr ratio and put in a 708 since I have it out. FYI just finished the exhaust, see ya cats!
