Hey all, just a quick point on 'gluing' the 5 0r 6 spoke wagon wheel' (what I've always heard them refered to as). Don't glue it in - it just makes getting it back out later harder. If the 'channels' it sits in are in good shape, the glue doesn't matter. If the channels have broken, then glue may work for a while but, you'll have to replace the multiport eventually anyway (I think they retail at about $120 , though you can probably get one much cheeper).
The part that does the job is the 1/16" raised 'bump' (think of looking at a cross section and seeing the Jefferson memorial [used to be on the back of nickels].) Be sure to use a silicone or teflon based lubricant (petrolium based will only eat, not treat the 'rubber') and apply it liberally. I've got about 5 things I'm working on now so, if you have any ?s - just ask (I try to get to my subscribed threads every day)
