Thanks for the reply Sandeep. I took my rear suspension apart last night and fond that I have 4 bolt on the spring plate. The previous posts only mention 3.
The bolt closest to the torsion housing is threaded into the trialing arm and the bolt does not stick through the inboard spring plate. The other three bolts go in trough the inboard spring plate, through the trailing arm and out past the outboard spring plate where there is a spring washer and a nut.

This brings up two questions:

Which bolt do you want to use as the pivot point for the TA to rotate about?
Why can't you slot the TA holes vertically instead of over sizing the holes in the spring plates so you have movement in two axis? (There's not much meat around the rear spring plate slots.)
