I cut the insert to 2.25" long. I drop it in, shove the lower bearing and seal in from the bottom drop the top bearing in and then set it on the spindle. Cinch down the spindle nut to hold the bearings in place. Slide the outer shell up/down until it fits where you want it and tack the inner sleeve in place. Dissassemble and weld. Let me know if you can't find an inner sleeve 2" OD.. I can send you a scrap piece cut to the right length.. just pay shipping (probably about $6-$7 from VA to AZ).. PM me if you need it..
