They don't make them, per se. It's just a length of tubing, preferably heavy-wall stainless, that the bolts go through on the inside of the mast, cut to the proper length, so that the mast walls don't compress when the nuts are tightened down.
The big question is how are you gonna get them on the bolts? I guess you could send a feeder line thru the bolt hole, exit the bottom of the mast, pull the sleeve back up to the hole then carefully feed the bolt through the sleeve. Ain't gonna be easy. I guess if you can remove the masthead and get to them that way, it would simplify the matter.
