Once I cleaned everything up, I bolted the plates in place and welded the perimeter. This made a bead on the outboard side of the top, front, and bottom side of the insert, and then on the inboard side of the back of the insert.
This insert stiffens up the mounting point and keeps the threaded inserts from ripping out like little volcanos. It also moves the load bearing pivot further back from the bolts which reduces the leverage that the rearset has on the threaded portion of the frame.
All in all, an easy project and it has held up very well in crashes. I spent a long time trying to figure how I wanted to reinforce this area, and this ended up being the cleanest/fastest/easiest way I could come up with.
