thank you for the link and info, do i try to get the rear end angle at this point when welding on the axle tube mounts or do i set the pinion angle at 0 degrees in relation to the face of the bracket and then adjust after engine and rear are in with the rod ends. If my thinking is off on this is there a certain angle that is a good starting point to set for a street driven car with a 460 ford engine and c6 trans, weight around 2500 pounds, thanks for the help on this i am a little nervous to start melting metal on these brackets
