Thanks gdads. Removed the rest of the spot welds except those across the top as i had no luck finding them. I ended up cutting the flange of the cowl and will butt weld the new cowl panel across the top. Started scotchbrite and wire wheel cleanup. Phosphoric acid is next. I’m hoping to get my hands on some Mastercoat silver to paint the plenum since I’m unsure i can clean the acid out well enough to use epoxy. Too many nooks and crannies.
While i wait for mastercoat, I’ll pull the damper operator cable and lubricate it. It’s difficult to operate the damper.
