Believe it or not, U-joints are not supposed to be straight.
The output shaft of the transmission should be parallel
with the pinion shaft, but not on the same line. Check
the specs on the u-joint. It will probably call for somewhere
around 1.5 degrees of deflection and should be the same
on both the front and rear u-joint. "Straight" u-joints
don't cause their bearings to turn, increasing wear in
one location.

I thought you should put the tranny such that it is in line with the
rear. This way the u-joints are straight.
