pinion angle

[68400BIRD]

I'm working on setting the pinion angle in my 1968 Firebird. I'm installing a 12 bolt that was originally out of a 1968 Camaro. The perch pads had already been removed.

This is what I have right now. The car is not on a level surface but the car is on it's suspension and is sitting on the ground.

Front u-joint cap that is closest to the output shaft on the tranny 2 degrees angling down.

Drive shaft closest point to tranny is at about 0 degrees.

Driveshaft closest to rear pinion has a angle of about 1-2 degrees angling down.

U-joint cap closest to pinion has a angle of 4 degrees angling down.

I put the driveshaft at 0 degrees closest to the pinion and the lower u-joint cap on the pinion had a angle of about 2 degrees angling down. I added in two more degrees angling down to get to 4 degrees and that put the drive shaft at 2 degrees angling down. If needed I could shim my tranny mount up a few degrees or shim the rear a few degrees one way or the other.

Does this sound close enough to weld it solid???
I also have this posted over on pro-touring.com

Thanks for any help you can offer.
