Couldn't find a specific section for steering and such so I hope this is OK to post here, I have a solid one piece riser top with tach mount that I bought several years ago, the centre to centre riser spacing is 4" and I am sure I took it off a Harley Davidson just cannot remember which model. I am now selling the item and would like to know which HD if any had the 4" riser bolt centre to centre spacing and a 1" diameter handlebar. Included some pics if that helps, any info would be appreciated.
