Assuming your're talking about the rear radius rods which have the integral spring mount which mount to each side of the rear axle assembly on a angled plate by two bolts, let's talk.
First, we have to provide a little more information here to get closer to answering your question.
1. what spring are you using?
2. what body A is it and is it sitting on a stock frame?
3. what rearend are you using?
4. My email address is email@example.com.
I'll be happy to spend some time on this but don't go whacking up a good set of 35-36 rods until you know what you've got to do.
