Do any of you know of a source for poly motor mounts for a '91?  Energy Suspension says "they don't make any" for my year model.  The Help Desk guy also said that the inserts they make for C4s will not work with the stock '91 mounts (reference number 2713).   The closest any E/S part comes to fitting my car is their part number 3.1121, which is a three-hole mount, but it's reference number 2421, not 2713.  I am totally shocked by all of this!  Am I overlooking something real simple?  If not Energy Suspension, then who?  Help!

Problem solved!  Energy Suspension does make poly motor mounts that will fit my '91.  They're the same as for a Camaro of the same vintage, but they're not listed under Corvette because ESP has not completed their field testing of them on an L98 Vette.  The guy at ESP swears they are the same mount and that he has sold them to several Vette owners without a single return.

great to hear you got your problem solved. amazing how many parts are the same for other vehicles and nobody knows it.
