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?

Have you called SPC? Great customer service for me. 1-800-525-6505 Sorry I don't have a Chevelle, but your part numbers are correct according to their website.

I have these arms on my 66 Cutlass. If I remember right, both the front & rear sleeves are the same length--6". If you're interested drop me a PM and I'll measure them when I get home tonight.

Problem solved, I think.....
Sleeves ARE the right length. 5" rear,6" front.
Couldn´t use the shims, with the 20* midsize plate,though.
The shims moved the upper ball joint outwards.
Thats why it was impossible to get negative camber.
We will take the car to the alignment shop and check again.

Thanks.Mike

Good deal.

I just measured mine. The adjuster arms (barrels) are exactly the same front and rear. These are the hex, billet adjustable uppers from Marcus.

Are they 5" or 6" long?
Since the GTO is also A-body,
do Your control arms have the same part number?
Part# 94324 Right,
94325 Left

Maybe the 20* plate has something to do with the different hex sleeve length?

Anyway,...problem solved!
Got the car back from alignment shop.
