Upon further inspection, the existing mounting bracket was FUBAR, so I took my angle grinder to it and removed everything inside the wind shield
As luck would have it, I had a crawfish boiler burner up in the attic of my shop that just so happen to fit inside the existing windshield.
I was not so lucky with the other burner. I could not get the angle grinder in to cut the welds.
As it were, I had to cut the windshield off, then the burner, and grind the rough areas down as best I could
I will try to soak the grate and windshield in apple cider vinegar to remove as much rust as I can, sand blast them down and repaint them with high heat paint.
Once that is done, I will find another burner that I can mount on the windshield and weld the windshield back onto the grate.
After dealing with removing the burners from the grates, I wire brushed the frame as best I could. There does not seem to be any areas that are rusted through, just surface rust.
I will give it the once over with an orbital sander and then sand blast any problem areas, give it a coat or two of primer, and then paint it with high gloss black enamel.
Once the frame is painted, I will drop the kettles in and that will be that.
