Ok firstly I don't have a Harley so can't exactly give you make model and year description but I have narrowed it down quite alot and I am sure someone out there will be able to help me.
The situation is I have a cruiser and wish to modify it so the custom world assumes it must be a harley. I am determined to to change my levers on my bike and the ones I want are pretty much only made for harleys. This is the levers I want the kuryakyn zombie levers. http://www.kuryakyn.com/products/112/zombie-levers
Chasing clutch perch, front master cylinder and controls to go on my bike master cylinder is a 9/16" and I believe the single disc bikes have a 9/16" master cylinder, will also need the controls as I believe the two mate together and don't look to great without the controls there (yes I realise I am going to have to be creative with the wiring) controls need to have switches also not just the housings, Im not fussed too much if they are black or chrome and would also be handy to know which levers I should be ordering to fit as well
