I spent like three days looking for a metric tape measure recently. Is this your photo? I couldn’t even find one on the dick rocket asshole’s jungle store.
That’s a good idea. Yeah, the trick I discovered in getting them off the mounting bracket without the chrome plating peeling is to grab each end of the bracket with vice grips and/or pliers (after you unscrew it from the drive) and just bend it down and away from the magnet. They usually come off in one piece that way, too.
