Went to two local hardware store, checker, and napa and none had anything that could work for the sleeve. Finally went to Johns 4x4 (local 4x4 shop...) and they let me root through an old parts bin, found a couple that were long and they cut them for free
Kevin finally called back and his solution was to put 1/2" washers (one on each side of the bushing) to keep it in place. Wish he would have mentioned that earlier or in the online directions etc...
Either way now I know and so do you
EDIT: Kevin said he is currently in the process of making a new metal sleeve.
