I think this is the last spot of rust.. Time will tell..
Before
After
Next I sandblasted the firewall and the inside of the cab.
Inside
Dash
Outside
Welded the patch on the outside as well.
Tomorrow, I will por15 the inside of the dash and the inside of the firewall. I need to find some sheet metal to start filling holes in the firewall. I will also start grinding the welds on the cab corners and prepping the rockers for install.
