spring plate adjustment

Is there a baseline to set irs springplates?
I putting the rearend together now on a sandrail and do not know where to start with the adjustment.
I know there isn't that much room for movement but would like to do it right. Thanks Tim C

The stock spec is 21°20' + 50'. In other words, with the pan dead-level the springplates should hang down about 21½° when engaged with the torsionbars, before they are lifted up over the stops. If your buggy is light, this may be high enough but generally you'll want to go more, maybe 25° or more - of course, the higher you go the harder it will be to get the springplate back up & over the stop.
There are 40 splines on the inboard end of the t'bars and 44 on the outboard end, so each time you clock the inside one way and the outside the other you'll change the angle by 50' (5/6 of a degree)

Thanks Marc, That is another situation you have reminded me of. I actually meant to say the adjustment where the trailing arms connect to the springplate. There are three bolts that connect them(I believe 3) I'm sorry for not being more specific. Thanks Tim

I would start at the center, put the wheels on and drop on the ground then see how the wheels point. If it is a street car you could run to the alignment shop but two long 2x4's against the tires and a tape measure will tell you all they could find out.
