i have noticed that with the poly mount over the stock it raises your pinion angle. i just need to know what that difference in height is so i can make a alum. spacer to fix this problem, also has anyone else tried this?

 

Most ppl I have seen , shave it down.....

 

I added 1/8" spacers to keep my -2° pinion angle.

 

AL SS590 M6, you wouldnt happen to have the dimensions for the spacers would you?? my car is in storage right now

 

Sorry, but no. I made them years ago.
