S&S Modified chassis


I picked up a S&S mod chassis in trade for some other stuff. Problem is, it doesn't have any suspension on it. I got the body and nerfs, had all the spare incidentals but don't have a clue on the suspension and have no idea what it uses.

Does anyone know what spindle number they use, and what length uppers? The lowers are the A frame style, been thinking of changing it to strut rod style. Has anyone done anything like this?
call A-1 race products, I think they bought  the jigs at one time, they should be able to help you.
