Does anyone have any info on how to do a rear disc conversion on a 60. I have read every article on the web and they all seem to be on 40's. Are the parts listed on the 40 going to fit on my 60 if I go buy them. Surley I'm not the first to attempt this knowing how crappy and expensive drums can be. I bought the crusher 4 months ago and love it. This will be the first real mod to it. Any thoughts would help!
