Replacing a body mount on my TJ

While working on my tire a couple weeks back, I happened to take a forward glance while under my Jeep and saw something I didn't like. The under seat body mount was, well, not mounted. It had completely rotted through and wasn't actually holding the body up. Evidently this is a big enough problem that suppliers are now selling them new. They're called a "torque box". I picked mine up from 4 Wheel Parts.

 Closer inspection revealed that there was no saving this. The box had to be replaced through the mid-section. For now the front and rear mounts are in alright shape. This was the one that worried me.

 I dropped my rocker guard and pulled the three body mount bolts (which were in terrible shape too) and what was left of the mount practically fell onto the driveway.

I spent some time trimming to get the replacement to match up. Bolted it to the frame, dropped the body down, and with a mix of welding and rivets attached it to the body.

I had to take a short break to go to get some new bolts for the body mounts since out of the three that came out, only one (in the picture) had any threads left.

That'll do, that'll do.
