Help with 72 Blazer Frame Issues - What are my options

[72K5CSTDarkOlive]

I posted this in my build thread but figured I'd hit a larger audience on the main Blazer / Jimmy board

I have finally figured out the modifications the PO (original owner) did to install the 36 gallon gas tank.

1. He removed the rear cross-member that has the 2 fuel lines going across the top of it.

2. He tack welded threaded nuts to the inside bottom of the frame rail so he could hold the tank with the straps that where on there.

3. He welded a cross bar going from the 2nd to last body mounts to compensate for the loss in reinforcement for removing the original rear cross member that sits in between the frame rails.

I cut off the threaded nuts using a sawzaw and dremel. Now I have to figure out a solution for the cross bar that welded to the body mounts.

If you're wondering why the 2nd to last body mounts are removed from the frame is because this part was riveted to the body so we had to cut them to get the body off the frame.

1. Do I try cutting it off?
2. Find some replacements and rivet or bolt on new (used) one on? Anybody know where I could find a set?
