Tom, I sent you a PM about it, which I listed here just in case anyone else is in need of the same information.
"The tool I use is actually very simple, all you need is a bearing splitter (some list it as a bearing separator), which you can find at any auto parts store (
NAPA,
O'Reilly, etc) or have shipped from some place like
Harbor Freight,
Grainger,
McMaster-Carr, or even
Amazon. Or if you have a local garage nearby, perhaps you could just borrow one for a few hours. Up here on the mainland most auto parts stores will loan them to you for free with a deposit to make sure you bring it back.
The bearing splitter goes over the shaft, backwards so the flat face is against the flat ridge of the collar, and then the screws tightened, this ensures it won't slip off. Then a flat piece of metal with two holes in it is placed over the end of the steering wheel shaft, and two standard bolts are used to connect the two. I used a piece of uni-strut so I wouldn't have to drill holes as they were already there, but a piece of 1/4" flat stock, some 3/16" (or even 1/8", like bed frame material) angle bar, or pretty much anything like that will work. Drill the holes so they're at the same distance apart as the ones on the bearing splitter/separator. Then you tighten the bolts down and it pulls the collar straight up. I have had some that were very tight come off with a 'bang' and some that slid right off, but it's very easy to use. To put them back on, I clean up the shaft with some scotch-brite or sandpaper and use the steering wheel bolt to tighten it back down.
I hope the instructions make sense, please let me know if they don't. I have three B4's and work on a lot of others locally, so I use mine frequently. If you have just the one car, I'd recommend just borrowing the bearing splitter to save costs, since you shouldn't need it often if you get a quality ignition switch. In your location I would definitely not use cheap parts since they never end up being cheap in the long run.
I have also not had to use the bearing splitter for anything else on the car.
Good luck."
