Rupp Enduro Replacement Clutches ??

[1funride]

I have a Rupp Enduro I picked up, it has the angled engine mount, it does not have the proper clutches. It has a centrifugal clutch up front, that drives a very small v belt similar to an old car alternator belt. The back pulley is just a v belt pulley. I was going to put a centrifugal clutch up front with a chain sprocket, then a fixed sprocket on the back, where the driven pulley would be. I'm having second thoughts on that and would like to have a belt driven setup. Are there any simple proven options to use, such as a comet 20 series clutch and driven that will bolt right on? Belt length? Will any of the lower cost TAV setups work if the back plate is removed? This is not a high end bike, just a bike for my daughter to ride at the MB reunion. Thanks Glenn.
