I recently put a new tranny in and checking the angles front and back I have found 5.25 front and 1 in the rear. What is ideal? I have 4.10 gears and a TKO 600. I do get a nasty vibration that comes on about 60 and by 70+ its getting pretty bad. The driveshaft was balanced by Keisler Engineering as part of thier kit so I am hoping to rule that out.
I have options to adjust the angles by either raising the crossmember or using a spacer in the trans-mount or both.
What would you do? I am out of my element.
