I ordered four of the mount bushings you pointed out from Mcmasters-Carr;
and they are indeed 'Barry' mounts.  It says right on'em.  However; they are
not the mounts sold in AS for $168.  There is no bonded metal in the center
groove that holds the support member, and I'm not sure what other
differences. I'm quite sure also that in the aircraft mounts the rubber is
'pre-stressed'; i.e., compressed into the metal parts before bonding.  And,
of course, they are rubber, which I believe has better energy absobing
qualities than neoprene.  But I suppose they will work.

I think the Barry's you have are Neoprene Al. The old Barry mounts were rubber 
so you had to order a 22003 instead of a 22002. Neoprene is stronger than rubber.
There should be a steel tube bonded through the center of these mounts. 
Is there not? If the hole in the steel tube is about .5 inch inch diameter 
they are Barry 22002.
