Sleeves for b21a1

[DieTek]

Found a company called L.A. Sleeves that has replacement cylinder sleeves for the b21a1, however they only offer it for the 91. What's the difference between 90 and 91?

did some more research and found that the year they provided was a typo. The sleeves they are selling are progressive auto sleeves and they have the proper sizes for the b21, they offer 1/16" wall, 3/32" wall, and 1/8" wall. Think im gonna go with this once i find out what size i need. They don't have a real price on there website but im gonna call and find out on monday.:cool:
