might could stay with your original swinger and use a china wheel and some spacers....will have to fabricate a disc caliper mount unless you use a cable operated caliper.....what is the steering stem length on your clone 50? that will tell you if you can use a China front end or not....I have quite a few 33mm conventional China front ends and a 25mm MR50 convetional front end.....you could go USD but then your talking much more money....post pics of the bike...full and close up ones of the front and rear
