So, started looking hard at all the ugly areas, and determined the only way to really know was to dig in...found quite a bit of really ugly underneath.
There are many areas of the frame that are damaged. Looks like the car was pulled from ditches a few times.... Many frame holes are torn open or damaged. The one under the passenger seat is absolutely shredded.
I'm gonna cut this section out and fabricate a new section.
The parking brake reaction bracket appears to have come loose from the frame at some point, and has been cobbled back on. Unfortunately, I can't tell what angle this is supposed to be mounted at. Does anyone have access to a clean photo of theirs so I can reference what angle this bracket should at? It would be greatly appreciated.
Tomorrow I'll sand blast inside the rockers and see what I come up with....
