Removed the old parts
Thoroughly cleaned bottom of firebox (since it was so convenient)
Assembled and installed replacement parts
The only difficulty I ran into was that the old screws had eroded from the back end of the burners and the tabs to screw the new ones down had the remnants of the old screws, nuts, and washers ... Read more kind of welded over the holes. The tabs were delicate and I was sure they would break off if I drilled them out. I ended up placing 6\" channel locks on the nuts and gently massaged back and forth a few times and they came loose.
The rest was easy breezy!
