Barry, Very nice work! I was initially worried about the strength of the clevises but computer stress analysis and lots of stock car racers have proven the design. There is a guy doing Chevy street rod suspension also with that style of upper A arm.

The ball joint holder is forged steel and is threaded for a screw-in "K772" ball joint.

Something to go with the adjustable upper control arm.

A wooden mockup of something to attach the control arms to.

The 2x6 on the left front is just to keep the wood gizmo from falling over.

The vertical 2x4's on the top represent the Alpine "frame rails".

I say make that thang out of oak and give it a try!

Why the cross bolt in the lower arm?

Bill,

The wooden mockup revealed a "minor" problem (no way to install the rear crossmember attachment bolts), so some changes are in the works.

The cross bolt in the lower control arm is where the lower end of a coil-over shock is supposed to mount. The fact that there is not enough room for the correct length coil-over shock may be a challenge

Barry, last week I said I'd measure up the UCA cross shaft. Sadly, the bolts on my 'spare' non-installed front end have consumed a couple impact sockets while resisting removal. Things don't look good without significant surgery on it, and it's gonna be awhile. It looks like I'll be ordering new, but not for a couple months at least. Sorry, man.

Ken,

Not a problem. I asked because it may be possible to create an adjustable upper control arm using the Alpine cross shaft. Won't do me any good, but it might be useful for those who are having alignment issues with the stock suspension setup.
