The build is coming along awesome. I don't blame you for wanting to get on the road. Drive that thing! I saw a short blurb in the back of the July 4 wheeler about a company called right gear (
www.rightgear.com) making a kit to adapt OEM 2001+ GM 14FF discs to older 14FF axles. The web site doesn't have anything on it, and I'm not close enough to that point to need to dig deeper. If the price is reasonable, that sounds like the ticket to me. Keep up the good work!
