Rear disc brakes are real nice, but I would strongly advise you before you make that conversion, to find out what your problem is now for sure with your rear brakes, because you don't want that problem being transferred over when you do your disc conversion.
No brake problem. I have an axle problem until I get my new one from eBay. The brake problem is minor because it's just a matter of flange size. Thanks again for your advice!
