My shop is 400 yards from the house, and weather is nasty here, so no measurements, but I had your problem last week.

 I rechromed a perfect grab bar, for my son’s K3. When I went to fit it, the stems were too narrow for the rubber grommet that fit the bar (centres were to close together). Turns out the K5 and K6 with the bigger “frying pan” turn signals have a larger diameter shank and stem, AND the dowel for the wires and the screw hole are further apart....... also, the base plate welded to the bar is larger on the K5-6.

Most important, I mentioned it here and one of the other Members swapped me an earlier one for mine! Worked out fine.

was your issue that the smaller brackets and rubbers were too small for the grab bar brackets?  what i'm getting at is if i get the smaller brackets and rubbers will they fit my k6 grab bar welded on brackets within reason to work?

I got a set of the smaller rubbers and stem to fit on the larger (K5/6) grabrail, but I had to trim the bottom of the rubber and then when mounted they were able to rotate and move........ when offered the swap for the correct K2/3/4 bar I went ahead.
