You guys are going to love this idea. It's not that complex either! I'm actually considering making these for people that want them.

First, here's what Pontiac bestowed upon us...



compared to the new stuff.



In the Navy's aviation community, we use what's called "safety wire" or "lock wire" in the civilian world. It's used to tie two bolts (with holes in them) together, so that if one starts to loosen, the other will get tighter, and prevent the bolt from coming undone. This stuff is so unique, it even has its own type of pliers.



I've used the same stuff to secure my new anchors for the 88 rear cradle bolts.



With M14 x 1.75 x 65mm bolts being completely impossible to find, I had to resort to custom fabrication.



I instead ordered M14 x 2.0 x 60mm bolts. I welded a nut to a washer, then welded the nut/washer assembly to a piece of 1" wide steel, then drilled 4 holes in the steel bar to thread safety wire through, then ran the wire through the holes in the beam that the cradle mounts to.




The safety wire prevents the anchor from moving through the beam while you position the nut in line with the hole in the cradle. The bar that I welded on is a nice handle on the nut so you can position it wherever you need to, and then it also keeps it from spinning around while you're torquing the bolts, because the bar is much wider than the beam.

All in all, it's a great design, if I do say so myself.

Then I welded the holes shut. It's a structural beam, and I didn't want to chance this being a weak spot, and I also want to keep "stuff" out of there, like leaves, sand, rocks, etc.





My bolts are torqued in and good to go now.

What would you charge for a set mailed to 20601?

Mine are out but they are worn thin in the middle. I could use something like this at the right price.

I did something very similar about 3 years ago, but used the existing witch hat nuts and installed them through the rear of the frame rail. Just took the cradle out again earlier this year and they continue to work great!

This is similar to the mounting nuts on the 88 front end. I was wondering why Pontiac didn't use them all around. Simple yet effective.
