Nice to see someone going this far to save one of these cars!
I have a similar project coming up on my '69 Cuda this summer.
Could I ask you to post more pics of your bracing setup? I'm trying to figure out how to brace mine up.
Basically it’s some old scaffolding....added some tubing under the rockers and cross bracing from left to right. Once the scaffold was squared up and levelled we bolted it to the floor. Squared car on the jig and welded it on. Pretty stiff.
