Work has officially begun! Unfortunately it's dark out but I've got a pretty good worklight to use. Came in for a break to eat dinner, but here's my progress so far:
Got the steering wheel off; my wood puller jig straight up crumbled, but fortunately there's always the BFH option

. Straightened up the puller as best possible, then sat on the seat and applied as much upward pressure as I could onto the wheel with my legs, and whacked the top of the puller bolt about 10 times. She loosened right up no problem.

Also pulled the fiberglass cowl and dash tin; removed the ammeter as per
ironman's advice. Then the choke, then the throttle, and lastly the 3 screws (4th one is broke and I plan to drill/tap for replacement). Came right off no problem, removed grommet for around steering column and separated the tin and cowl. Turns out there's a lot of crud under there so good thing I can clean it!

Next step is to remove the solenoid, my light switch, the key switch, 4 bolts holding the hydro shaft mounts, and the 4 main tower bolts. Tower should then come off no problem. Going back out to do a bit more work so should make a little more progress still.
