Today was a spending spree.
I've bought a 2k pound trailer spindle/bearings/hub to update to a modern axle/wheel/tire. I'll burn it in and reinforce it so it'll be much stronger. I will then use a 15"x4.5" drag wheel that doesn't require tubes and accepts a regular car tire available at any store nationwide. Once it's mocked up I can determine proper offset and order the wheel. Tire will be a 175/65/15 and I'll do a custom fender. It's 1.5" shorter than the original but this isn't an offroad rig so it'll be fine.
Bought the swingarm bushings, bolts, nuts.
Got a new seat.
Got a 20 ton hydraulic press to do it all.
New bump stop and bushings for shock mount.
The plan is starting to come together.
