Back with a minor update
FINALLY got the rest of the trim piece out of rhe tubing - took a bit of "negotiating" with a spade drill bit. As far as I can tell, it was just somehow amazingly well wedged in there (no signs of glue/JB weld, etc).
I had a couple more quick questions though. When my co-worked drilled out the broken bolt from the cookbox, a small part of the inside finish (near the bolt hole) was removed. I've read that you should not use paint (even bbq paint) to recoat it, so what should I use instead to prevent rusting?
Also, if anyone would be so kind - what are the dimensions of the slats/brackets for the wooden side tables? I will have to fab something up (or find parts from another grill), as the only replacement parts I've found online are the top portion of the durawood stuff (i.e - no flip up portion).
Thanks!
