I got my rear radius arm brackets installed and adjusted. Here's the backstory [link]. So, was it worth it? Meh…

Success! A combination of different jacking points and a large tapered drift into the bolt holes did the trick—after I figured out which end of the endoscope was up. I have to confess it never occurred to me that the orientation of the camera was important.

The business end of the endoscope is a small diameter cylinder and there's no indication as to which is the top and which is the bottom. To determine if I needed to lift the body up or pull the trunnion down to align the bolt holes, the camera needs to be oriented correctly. It was only after I had been making my adjustments opposite of what they should be I yanked the endoscope out of one of the bolt holes and caught sight of my upside down garage on the screen. Duh!

I expect I'll need advice when I begin adjusting my toe brackets; the instructions are useless. Stay tuned.

Original factory subframe bolts had tapered ends to help line things up.

Try loosening the trunnion on the subframe, lining everything up with the bolts inserted, then doing it all back up again.

That's an excellent idea. Meanwhile, I'll see if I have any similiar sized bolts in the bin. I can grind the threads off and add a taper. Hope in my next post I'm not whining about stripped threads.

There didn't seem to be any body twist when I unbolted the trunnions. The bolts came out smooth and straight and the jack stands hadn't been moved. Yeah, don't want to strip the threads. I guess I'll continue to try different jack stand positions. Maybe load some grandkids in the back seat too.

In order to install my new adjustable rear toe brackets, I had to remove the two bolts per side that secure the rear subframe trunnions to the body. I had the rear subframe on jack stands when I removed the bolts, and they came out smoothly without binding. When it came time to put the bolts back in, the bolts on the left side went in without a problem. The right side bolts, however, don’t line up with the threaded holes in the body

 

I loosened the left side bolts and disconnected my sway bar to allow movement between the swing arm, body and the subframe and tried moving the jack stands around. I even tried placing the jack stands under the very rear of the body to allow the subframe to hang unsupported, but still cannot get the holes to line up.

 

The picture was taken with an endoscope from inside the trunnion hole with the threaded body hole in the background. Has anyone experienced this problem and does anyone have any ideas how I might get the holes to align? Thanks!
