I use exactly what your describing. I bought mine at R&B cycles (Big Dog Dealer) in Nashville. $52 plus tax. They actually suggested them over the set screw "BDM" covers. Said guys were loing them. I have had mine since August and they havnt budged. I had to loosen the ignition the get the two inside ones on, so it is impossible for them to come off anyway. I think they were S&S brand but cant remember for sure.
