Sir, i cant find any problem in sending u ur desired stuff but keep in mind when u swap out ur current system wd another current system it will effect the engine timing and as in result heatup, knocking, not getting good mileage,etc..... i second u that its the bolt on fit for ur machine... Sir, have a thorough discussion before taking any action.... ill also consult sum gud mchcanics of ROAD MASTER till Saturday kay what to put in
