SPC upper control arms for -66 Chevelle

[osdmike]

Hi! I need info what length the adjuster sleeves are,front and rear,(see pic.) for -66 Chevelle. SPC arms.
I´m not sure I got the right length.
Front is 6",rear is 5"

Part# 94324 Right,94325 Left

We had the car at the alignment shop.
When setting the caster angle +5*, it was impossible to set the the desirable camber at -1,25*.
Camber stayed on the + side.

If the sleeves were shorter, it would be easier to set the correct camber.

Lower control arms are CPP and the measure is consistent with the original to what I have heard.

Any suggestions?
