Just when you thought it couldn't get any better , my old dusty 1985 dave morgan chassis tuning manual comes out of retirement, maybe this is the "data" he was referring to.......hmmmmmmm





you must just look at pictures and don't read anything Dave has stated that is they way they done things back in the 60s. he has said many times after testing and solving many vibration and drive train issues he found it not to be correct in his opinion. he now recommends setting of of the motor/tranny center line. nice try though. it must really make you think also take a look, the motor/tranny center line is on the same line as the drive shaft......



Tony if you notice that the drive line is in line
in that pic... same way I set up my chassis stuff,
then I dial in the pinion angle on the drive shaft
just like the pic, which gives the front and rear
U-joints just a bit of angle for lube purposes




with that pic it further proves my point. you could pull that shaft out and still set your angle



Actually Tony if you look at the pic, that one is
set up INCORRECTLY... if you notice that the front
joint is in line BUT the rear still has the pinion
angle on it... you want BOTH joints to be in line
while under load... in the case of the pic, as the
pinion rotates up it will pull the rear into line
but the shaft will move upward moving the front joint
off of the same line.... when I set up my chassis/engine
I use a laser that I made up to fit in the rear main
of the engine and set the engine and pinion all in
line.... then rotate the pinion down which will give
BOTH joints movement for lube while not under full load
