Is there a how-to on this or does anyone know how to set the pinon angle with adjustable uppers on a Cobra with a SRA rear? What are the specs that it should be? Thank you in advance!

I think 4-5 percent is how you set it for drag strip duty~ but like 3 for highway? I might be off just trying to remember~

You use an angle protractor and you figure out the angle between the chunk and the driveshaft, thats the angle you are aiming for.

Measure the driveshaft angle coming out of the trans and match that driveshaft angle going into the diff.

Every time you change the diff angle you have to re-check the trans angle because it will change.

No help from the SRA guys, huh? See, you just lose so much camaraderie when you put that wagon axle in...I kid, I kid. However, I know tons of guys have done this, so I'm bumping this for you.
