I have a UMI body mount TA and I was wondering what I should set the PA at. In the instructions it says to set it at 0 degrees. The car has a TH-400 with drag shocks and all tubular suspension. Also what would be the best way to set it, I bought an angle finder from Home Depot to use.

I did a search when i put mine in and found too many different ways to set it. The way i did mine was i put the angle finder on the face of my crank pully to see the angle og my motor. Then put the angle finder on the bottom part of the TA (big flat piece the bolts go trough) and find that angle. Then find the differance of the 2 and thats your pinion angle. I got mine aet at -2deg. Best part of that set up is the car doesnt need to be level because no matter where your car is at, the 2 mounted parts on the car will always be the same.

You are correct the pinion is going to try to roll up and be parallel to the track. This will cause the load to be placed on the suspension and lift the car and plant the rearend. The driveshaft etc is irrelevant because it can be mounted higher or lower than the pinion .

Madman , shouldn't you zero the angle finder? Where is the "zero" or neutral point? Here is what I am after...if the Tq Arm was put in with "X" degrees down up or doesn't matter really...how do you get the rear to Parallel then go 2* neg or down?
I was gonna ask you this yesterday and it slipped my mind.

So MADMAN, i set my pinion -2 deg. so under WOT my pinion is gonna be parallel to the ground? If so i get that point. Now on my specific car i have poly motor/trans mounts. In turn raised up my motor/trans a tad. So what if that makes my driveline angle in a bind? Wouldnt i start tearing up my u-joints?
