pinion angle

So is the 5 degrees true for SS springs as well? I'm going to start over on my angles. Bad vibes from 5K up in high gear only. So if I have 1 degree down on the 904 output shaft and 3 degrees up on the pinion what should my shims be. This is not u-joint angle measurement. I measured on the pinion yoke. Do I need 6 degrees down on the pinion? What about the pinion snubber
Thanks,

Right now you have a 2* up angle which is BAD!

If the output shaft is 1* down, the pinion needs to be 1* UP to be a 0 angle.

If you want a 5* down pinion angle, you'd roll the pinion down so it's at 4* below level.

I've had a SS spring car need 9* down... 5* is not a bad place to start. You likely wont find a 7* shim to correct the current angle issue. The locator pin won't engage the perches, too short.
