I was able to get a little more done last weekend.
I cut out the horrible patch job on the outside of the drivers side frame rail, blasted, primed/painted and boxed in with 16 ga (I think? may have been thicker) sheet. I still need to do the small portion in front of the cross member mount.
After spending a couple of hours fighting with all the spot welds trying to remove the brackets in the engine bay I gave up after seeing how weak/ think the metal was. It also became pretty clear how flimsy the shock tower support must be. So, I cut a healthy chunk of it out (pretty close to the perimeter spot welds) and added new sheet (22 ga) along with some 3/4" tube. Once I get around to the fixing/ replacing sections of the firewall I'll add bracing to the back of the towers to the firewall.
Also shaved the drip rail. Still very much a work in progress
