So I bought some 2 degree wedges and installed them. The thicker part of the wedge is towards the back of the car and the thinner facing towards the front. Now I have -1 to -1 1/2 pinion angle.. at least according to my made in china magnetic angle finder. oh, but wait, when I measured and got the -3 I had the engine and trans in. Now the engine and trans are out.. would this effect it? Last edited by Mopar_Mike; 08/15/09 10:47 AM. RS23L7 4-Speed

Set the pinion parallel to the transmission as a base-line, then pivot the pinion downward 5 degrees. When the engine and trans were in I was +2 with the trans and -3 at the pinion. I use caltracs and they say be -3 overall. So I bought the -2 degree wedges hoping I can get to -3 overall. Sorry I did not explain that. RS23L7 4-Speed
