I went out to the garage, and looked at the brackets on my Whirly Jig. The rear brackets look identical to the ones in your picture. A Cuda was the last car that was on my Whirly Jig before I bought it.
Thanks for the info everyone! Now that we have the brace tied in with the lower bumper bracket (bolted into the hole on the frame rail) it does seem more solid. Just can't get up the nerve to rotate it over on the side just yet. I see some people talk about rotating it over on the side (straight up and down) to install the subframes, but it just seems like that would be better done while on jack stands??? Am I wrong?
