Because I'm a cheap bastard, I found a cheap Chinese cold chisel at the hardware store, that happened to have a 3/4" hex shank. You can verify the fitment, by placing it in a 3/4" socket at the same hardware store. I cut about 2" off that, to use with a 3/4" socket. And the cold chisel's only about 6" long now instead of 8. That was around $7.00, and the appropriate square-drive hex socket was closer to $25.00. Cutting a 3/4" cold chisel with a hacksaw isn't an option. Fortunately, I've got access to a monster bandsaw at work, that cut thru it in about 4 minutes. Then I cut another chisel down that was in my toolbox for the 12mm drive. It was faster than a second run to the hardware store. And cheaper.
I just swapped to chrome sliders last weekend, and it would've been a cakewalk if I had the right tools BEFORE I started. A trip to the hardware store, the Harley shop (for seal kit and fluids), and the "project" only took about 3 hours.
