Waiting on parts to come in, but was able to get a little more done in the meantime. I bought an old flat bottom GME tank on eBay the other day, and was able to get it mounted before I took it up to Estes to look at some paint ideas.
Mock up. Looks fine to me!
Pilot holes...
3/8" holes...
Done
Was also able to do a threaded plate for my right side/kicker side, foot peg. Drilled...
Tapped, and done.
