Pat, that is precisely what I came up with too. I went around work looking for a stray ball bearing today, and we keep tossing old stuff out, so I am going to the hardware store to see if they have one. Our Service Manager tells me they carry different ones (I can't imagine why a hardware store would carry them) but if not, I will just tear something apart that has some bearings in it and get one of those. I like your idea about loading it with a set screw to increase/decrease pressure. I will make up a tube to hold the bearing, spring, and set screw, and weld it to the bottom of the shift handle, so it rubs on the larger of the two brackets. Some little depressions drilled into the bracket for the ball bearing to rest in, and I should be good to go.

Thanks for the tip.

Don
