I JUST broke a ES motor mount or two. i looked at the back and there is a part number. THIS IS NOT THE PART NUMBER!!!! DO NOT ORDER ANOTHER ONE FROM THIS NUMBER. for example the part number on the back of my unit says 1114. they do have a p/n 1114 and it is NOT THE SAME and has 1108 on the back of it. ES says the number stamped on the back of their parts HAS NOTHING TO DO WITH THE ACTUAL P/N OF THE PART. what i wanted for my early chevy is p/n 1117. god only knows what it will say on the back, hopefull 1114 like the one i have. talk about F'd up!
