Nope - Welded on and the frame/cart looks the same but mine had a huge rusted out hole 'tween firebox and cooker.........it had those bars in Fire box too but I cut them out and I tossed the crappy fire box lid and put flat 1/4" top on.
Started sanding this morning. The firebox has rust under the paint. Gonna sand it all off, hit it with a rust converter and spray with VHT header paint. The rust on the interior is pretty much all surface. The firebox deflector plate is deeper than I thought it would be. Gonna take a while to get to bare metal there. Once the exterior is sprayed with VHT it's gotta cure 7 days and then I can season. Will post up pics later today.
Sanded and wire wheeled for about 4 hrs yesterday. Got 4 coats of VHT headed paint on the firebox and 2 coats on the cook chamber. I got the inside pretty clean. The grates are currently sitting in a tub of vinegar and salt. Will take steel wool to them in a few days.
