I cut out a few rusty sections of the floor a few months back. Yesterday, I finally started replacing them. Here’s a shot with the 1″ square tube floor “joists” welded in place.
Luckily an L shaped piece of 14 ga steel fell into place, after a careful rotation.
I’m hoping a rectangular piece is next.
Overhead welding sucks, so I’m going to drill holes in the sheet metal and weld to the joists from the top, rather than from below.
Here’s a blurry pic of the new panel with holes drilled and weld-thru cold galvanizing primer. The primer has zinc in it, to minimize corrosion in the space between the panel and the support pieces.
I also removed the cowling covering the rear portion of the engine and transmission and cleaned all the rust off of it.
