The "Tuxedo Seven" mod is pretty simple to do, if you want to shell out about 60 bucks for a premade plate or make one yourself. You'd need a dremel or oscillating tool to cut the left side engine case (small cutting wheel on a drill ina pinch), compass or micrometer to draw nice circles on some sheet metal, and the ability to drill holes accurately. I did it myself and it was pretty easy. I didn't have to goop up the gasket or anything. I just used a light coating of RTV just to make sure it sealed 100%.
Worst case, you order a plate if you can't position it yourself after making a couple of bad plates. But a trick is to drill all 3 holes in one set, drill 2/3 of the other set (either way, doesn't matter). Now use feeler gauges to check your stator clearance. If it needs to be shifted, use set of holes that you only drilled 2 of the 3. One hole as a pivot, slot the 2nd hole to tweak the stator position (think cars where the alternator is used to take up slack in the belt), then drill your 3rd hole accordingly. Bingo. 2 slots can allow things to shift if anything loosens. 1 slot and 2 normal holes can't shift.
Gap your pickup coils while you're in there.
If you think you need to do the balancers, maybe just pull the engine but that's more work than I wanted to do.
