hello, i've been lurking around in the shadows of this site for a few months gathering info and tips for my build. i was wondering what happened to the idea about the left side gearing. i lost the thread, i was into it for 25 pages and it seemed to disapear. i like your input about it being cost effective and simple for a diy application. are you making any of those awesome gas tanks to sell? or are you water logged? have you thought about selling plans for them?
