Driveline angles

[T(urd)67]

I'm currently working on a 4g63 in a fox body build. My question is what kind of driveline (engine/trans) angles did some of you guys use on your rwd projects? I currently have about 2-3 degrees of angle with the tailshaft pointing down (measured at the tailshaft). I might even go another degree down if i can get away with it, to help lessen the amount of angle in the u-joints. The motor is sitting a little higher than I like b/c of oil pan issues with the k-member/steering rack, so I'd like to run as much negative driveline angle as I can safely, to keep from having to run a crazy pinion angle at the rear end to straighten it all up under load...

Thanks for any help!
