Wouldn't worry to much about straightening it out. The rubber flexes plenty and is primarily ment to hold the bearing in place without transfering noise to the frame (interior). Nice driveline pic - I took the following pic, then came in and read your thread LOL
I also posted some info in your pic request thread.
Also just for some additional info - This is the info from my daughters truck:
Tranny output shaft angle: -5 degrees
1st driveshaft angle: -4 degrees
2nd driveshaft angle: +5
Pinion angle: -2
If I did my math right, I should have an pinion angle of 3 instead of 2, but oh well.
(diagram of her truck looks VERY similar to the one posted in your airride link)
