Need an Angle Finder

[DETROITMUSCLE]

I am looking to borrow, possibly even buy, an angle finder so I can properly set up my Torque arm. Please let me know if you have one I could use

do you have an iphone?
are you gonna do driveshaft angle or driveline angle?

Don't trust the iPhone...we tried using that and it's something like +/- 3 degrees.

But Harbor Freight has 'em cheap...

Honestly that was gonna be my next post, I don't know how its supposed to be done and I don't have an iphone. Harbor frieght I could do though.

on an auto just doing the driveshaft angle(vid on bmr's website ) seems to work ok. That is driveshaft vs pinion angle
the way madman and some others say to do it(I do it this way) is the pinion angle vs chassis angle.

I've always done the driveshaft vs pinion angle. What do you reference on the chassis for the madman method? Also, what is the correct angle using this method?

Well I did some research and I am gonna try it the way Madman suggest because not only is that easier but I trust his judgement. All you have to do it set the car on level ground and measure off the yoke and set the rear at -2 or -3 degrees whichever you want to start at, thats it. Now I just have to get an angle finder and get to it.

i use my subframe connector vs pinion. the SFC are pretty much level with the chassis so thats what I use.(the car isn't level with 28's)
I run -2.5. If I set it to -2.5 using the driveshaft method the car won't leave the line at all
