I'm going to be getting my rear suspension in soon, and I am trying to figure out how you weld the tabs to the axle without the rest of the drive train installed.

It is an air ride airbar. How do I know where to weld the tabs on top of the axle? They are going onto a multi-leaf rearend.

I had thought about putting my leafs back in temporarily to place everything, but I must have gotten rid of them somewhere along the line of the build.
