ISO original GM new drivers side LT1 Motor Mount. I know it's a long shot but the aftermarket mounts suck and the poly mount vibrates too much. Thank you.
part number 22188799

 

An original new GM LT1 mount is extremely rare. The part has long been discontinued. GM dealers no longer have them; at most, they're either NOS or leftovers, which are extremely rare. Try a vin search using https://carfast.express/en/vin_decoder to confirm compatibility and possible replacement OEM numbers. Sometimes GM changed them, and there may be an alternative original mount for your VIN.

 

Thank you.
