Hello all, new to the forum, but have a question regarding driveshaft length. I have a 1966 Coronet 440 with a 440ci and a727 from a 72 Charger as well as the factory 8 3/4 rear end. What length driveshaft should I be looking for and where should I go to get it? Also, any help on finding the right engine mounts would be valuable as well. Thanks!
