NO ROOM. lol. any advise or input would be great. thanks for your time and help.also motor plate in front and poly trans mount.
The idea is to have a 0 angle with the vehicle under power and the exact amount of drivetrain deflection will be different for every vehicle. That said, if you end up with -2 degrees static pinion angle, you should be OK due to the tendancy for the pinion to 'climb' the ring gear under acceleration.
