Thanks anyways joey but too late. Modern had a set in stock for a good price.
I tried to tap the nutserts and failed. They came loose inside the frame. I had some hexicoil so I tapped the frame anyways and installed that. The bolts held and are tight. Kind of sketchy but I have a back up plan.
Note: the drivers side came out just fine.
Plan A - I have some bolts, and I'm going to weld them to a washer then weld a piece of metal (3"s) to that washer. Then tie the end of the bolt to some bailing twine and fish each one through the frame holes. That way alls I have to do is stick a nut on them.
Anyways, here's what she looks like all together:
Just needs an alignment to cure some death wobble.
