What is the correct way to check to see what pinion angle is? Putting a angle gauge on the bottom of the punkin as it sets on all fours or do you also check and see what angle the drive shaft is going into it and do some calculations?

I SET MY PENION ANGLE WITH THE CAR SETTING LEVEL ON THE FLOOR AT AROUND 7 DEGREES.

Keep in mind that there is a big difference in pinion angle between a leaf spring car and a coil spring car! Leaf spring cars want avout a 5 to 7 degree down pinion angle whereas a coil over car needs about 2 to 3 degrees of pinion angle. The reason for this is because a leaf spring car has the leafs preload - kinda like a wave shape or form wheras a coil over car only has the deflection from play in the bushings! Hope this helps!
