thanks Sport ---

Now , we also have the crowd that uses the pinion measurement and the D shaft measurement....will their results be the same numbers ?



No, You only gave One set of numbers between the pinion and the driveshaft.

Those were 4* down Shaft and 10* Down Pinion, witch would give you a "Driveshaft /Pinion angle of 14*

I will Edit my post to include that for a perspective.





OK, here is what i meant ---

there are people who measure the shaft and the pinion.

your method is the Trans and the pinion. correct?

here is what i mean :

notice this guy doesnt include any trans angle




And Did You notice, he's working with a 2 piece driveshaft. He states this works on Mustangs with a 2 piece shaft from 2005 on up.


Dont get me wrong You can get by with using the driveshaft. Its just not as accurate.


In MR.Pbodies car, he built his engine/tranny driveline paralell to the pinion. He and anyone else who does the same can accurately set the pinion angle off the Shaft.

People with Unmolested drivetrains can set the pinion angle off the shaft and still not have problems. Though the accuracy of the true pinion angle wont be known. As long as your getting a negative angle reading between the two of 3* to 5* or so. The U joints will do thier job and you wont notice anything most likely.

With a modified car such as yours, I think one can see you wouldnt want to measure it off the Shaft.

Your current measurements between the shaft and pinion give you a neg/-14*


Your current measurements between the tranny centerline and pinion give you a neg/-9*


Both sets of numbers are telling you, that your pinion angle is to far negative. If your measurments are "correct"

With your combo you dont want your pinion angle set to a positive angle. On Your ride, I wouldnt use the Shaft.

If you do, You may get a Shaft Attack.
