open 8 3/4 carrier

I know we shouldn’t have a discussion in for sale ad, but it seems pertinent. The spacer in an open carrier will slide right into spool. You just slide in in before you put it in the housing. Then slide the axles in and adjust the end play as normal. Length wise it is just like it was still in the open carrier. Now it is smaller than the cavity in the spool, but it won’t move around much and it is so close to the rotation center point balance isn’t an issue if it is a bit off center.
