The image I originally posted is incorrect - please forgive me - I re-posted the image above and a link below to the product. I purchased the arms from Jegs. There are two sizes. I tried the smaller - no good. They are not to be run with more than one inch of exposed thread beyond the jam nuts. We could not achieve this with the shorter arms.
Specialty Products 92556 SPC Race Style Adjustable Upper Control Arms
We have it all bolted together just to align to the spindle and get the thing back on its wheels. On the rack everything cycles very smoothly, with no binding, from full bump to full droop and we have not had to modify the aluminum panels.
That said none of it is set to spec, everything is prototype, but it all looks very promising. We had to move our machine shop so we had to pull off, but hope to be going again next week.
We want to try to run the cross shaft directly against the upright - we have not studied that geometry yet with respect to maintaining the original timing.
Bob, if you can give me any insight here it will be appreciated. Specifically - if we pull the alignment shims and mount straight to the upright, will we affect the timing such that it could not be adjusted in the arms provided the arms have enough adjustment? It is the location of the upper pivot with respect to the lower I am concerned about.
The SPC cross shafts are not offset so we will have moved the pivot point inboard by the amount of the original cross shaft offset + the thickness of the alignment shims. I just don't quite have my mind around this yet.
If the proper timing cannot be achieved, we will either run nominal block spacers behind the cross shaft or use the original Moog cross shafts or a combination of both and then fine tune with the arms.
I purchased Howe low friction ball joints (upper and lower) and some Energy Suspension dust caps. I supplied Howe with the the part numbers specified in the build manual and they sent me the joints.

I have a caster camber gage that threads onto the spindle so that is how we will set it up. Ordered the Penske's yesterday.
Is it all going to work? - I have no idea, but we are entertained and I am very excited to try it out - it operates very, very, smoothly?
Bob - you guy's built the coolest thing ever - it is a joy to work on - thank you.
