There is still some final noodling to do with respect to the rear axle suspension. My original plan was to make the axle-side of the Panhard rod mount a double shear affair. The big RHS piece in the photos from my last posting (just above) would have supplied that. However, their really isn't enough space to do it the original way and still be able to adjust and maintain the Panhard rod with reasonable effort. It's getting crowded back there.
The axle clamp itself fits nicely. I have about 2-1/2" clearance on droop between the bolt heads and chassis. In reality, no more than 2" is expected, so I should be OK.

In place of the double shear implementation, I'll be doing single shear as shown here.

The design consists of the weld-in, tapped, bushing I machined, and a 5/8" Heim joint dropped to 1/2" diameter by a set of high misalignment bushings, plus a grade 8 flange bolt and a thin retention washer. In truth the Heim joint can't go over the head of the flange bolt, but the thin washer supplies a little "belt and suspenders" reassurance. I'll need to use the semi-permanent Loctite compound on the threads of the tapped bushing. The flange bolt threads 1-1/4" into the bushing and I think that should be adequate.
The weld-in bung and jamb nut will secure the Heim joint to the 1-1/8" DOM tubing of the Panhard rod itself.
I'm making a second axle clamp which will accept a triangulating tube going from the DOM tube on the axle mount to a tab on the second axle clamp. That's where I plan to absorb lateral forces from the DOM tube of the axle-side mount pictured above. So, I still have some fab work to do.
The adjustable coilover mounts I ordered came today by UPS.

The general product is of really good quality, but there is one issue I'll have to solve. As shown in the vendor's parts catalog, the threaded tubular boss (you weld it to your chassis) goes all the way up and down the threaded shaft. However, as shipped, the threads on the boss are such that the shaft only goes as far as you see in the photo below.

That's not going to work for me. I need to have 1" adjustability on either side of the boss so I can adjust the height of the car without pre-loading the coilover springs. It's 5 days for shipping each way if I send them back to the maker to be fixed. I can get a 1" x 8 UNC tap in 2 days. I think I'll just finish the threading myself.
I'm trying to buy parts where I can instead of making everything myself as a means of cutting down on the time necessary to complete my build.
