The bus sustained a front impact to the side of the front wheel well area. Here's the area behind the front door. Lots of bondo, bad welding and rust. This area usually rusts anyways, even without the poor repair job.
Unfortunately there were several areas with poor repair and over the years the rust did its job (as best it could) to get rid of the bad welding and bondo.
The worst area is the front jack point, where they did a crappy job welding in a replacement jack point (or tried to straighten it out) and there is a bunch of mutilated metal in there. It really needs to be cut out and a new section welded in.
I am using KYB shocks up front, hopefully they aren't too stiff. (In the picture my dog is looking under the bus for lizards and snakes.)
