depends which ones you are looking at, the shaft that comes up is just over 1/2" the shifter i bought had a 1/2" collar.. which of course didnt fit, so i had to bore it out.. i stepped it up to 9/16 and that did the trick, not a perfect fit, so there was a hint of rattling, but a quick coat of e-tape around the shaft fixed that problem. posting links to the shifters would help figure out if it will fit or not, it really comes down to how much work you want to put in.. you can make just anything fit if youre willing to put in the wrench time

also keep in mind that theres that square collar over the shaft, so unless your shifter fits over that, youll have to remove it, which leaves the shaft exposed (which is pretty ugly) or let your shifter rest on it
