HillJack, I've been through this before and though that I had found all the tech information associated with pinion angle combos/options. Then I was referred to http://www.vibratesoftware.com/html_...king%20angles: (sorry for the long URL) Take a look at this...it provides a lot of tech detail regarding allowable working angles, and acceptable drivetrain geometry options (i.e. up, up, up, or down, up, up, etc.) Anyway, I've got the transmission pointing down about 3.5 degrees and the rear pinion also pointing down. I set it up per the guidance in the URL above and eliminated my driveshaft vibration at 70mph. My rear working angle was about 6.5 degrees. I used adjustable upper control arms to reduce this angle. Bottom line is that the URL address above was the most comprehensive breakdown of drivetrain geometry problems that I have ever run across....hope it helps......Scott
