hi jim,

     yes thank s for the info. acs said they had 12 isolators. left in stock. apparently vip who makes these went out of business. their web page and phones gone/disconnected.

I used these https://www.aircraftspruce.com/catalog/eppages/dynosandwich.php from spruce on my o-235 mount with a Yo-233 engine on my 650B. It's not running yet, maybe in a few weeks but it mounted perfectly.

PS: they are the same you are looking at

doing internet search, found that the vip 50402-5 rubber isolators cross reference to 

lord J-7402-16.  $148.75 x4

barry 94150-01. $117.75 x4

avbl aircraft spruce and in stock. need to call to verify diameter. 

hope this helps anyone using a lycoming and zenith mount.
