thanks for the replies.
I think I did a poor job of describing my situation so I will take another crack at it.
Starting from the front of the car and going back:
My transmission has a slight down slope.
the drive shaft points upward to the differential.

Here is what I am confused about:
The differential input is higher that the transmission output, which is what causes the drive shaft to have to slope up to reach it. Do I need to have the differential point down towards the transmission ( I can do this if necessary by adjusting the control arms ).

Thanks again for your help and sorry for any confusion.
