Note that 3.5 degrees is required to get the pinion angle to be 1 degree with the transmission pointed down at 4.5 degrees. The operating angles in this scenario are 7.5 (front) and 6.5 (rear)*. Not even remotely acceptable. And as the pinion climbs under power the rear angle gets even worse (8.5).

One way or the other I believe the situation with the trans angle needs to be addressed.


* Assumes a 3 degree driveshaft angle. May be worse than that as connecting a 4.5 degree low tailshaft with a 3.5 degree high pinion will require a pretty steep angle. If worse than 3 degrees (likely, I think) the operating angles also become worse.
Using the calculator you originally posted 4.5, 3, 3.5 equals a perfect setup. Working angles of 1.5 and .5.
Even if the drive shaft raised a degree due to resetting the rear it still would have worked, 4.5, 2, 3.5 = 2.5 and 1.5.

Now, using 1.4, I cannot make it work. I think I should have left it alone and fixed the rear end.
