About to start my IRS swap on the mclaren after I do the pinion seal. Anyways there's a rear mount bracket that swings into the frame rail near the gas tank. From why I understand the frame rail is empty that's why it bends. Should I open it up from the top and insert any extra bracing or metal in there to prevent the frame rail from collapsing or rolling the bolt holes over time?

All suggestion welcome thanks Cafords

When I did my boys hatch I used fat washers and long thick bolts that went through the frame to the inside of the car. Simple and after a lot of dogging, still no issues at all. One thing I would have done a little different would be a plate on top and bottom of the frame under the fat washers I put in.

This is how I did mine. I used a hole saw to get through the trunk sheet metal so I wouldn't crush the already weak frame rail. I also didn't want to cut too much because the trunk floor boxes the frame rail. Another reason to do it this way is that you don't have to drop your gas tank.
