I have been having problems with finding a lens for my cx500. The one that it had in it was too small or the retainer was the wrong part perhaps... Anyways. Can anybody tell me what the part stamp is on the headlight bucket. Are the buckets the same for the cx500 as they were for the gold wings or the 650s of the same years? My bucket says HM-27M-S on it and the retainer says HM-18M-S. Are these the right pieces and do they correspond to each other? Thanks!
