Hi, I'm in the middle of replacing my motor mounts and I heard something about there being a difference between the two? My new ones have the same part number and I cannot tell the difference between the old ones in my car.

 

Left and right are slightly different, with different part numbers.

 

I was referring to the rubber mounts with the metal shells around them that bolt to the k member. They are different?

 

I am replacing mine as we speak. They are functionally identical, but there is one small corner that is trimmed from the bottom of the pass and driver side. I guess it makes it more flush against the k-member when looking from above.

 

Inserts are the same left and right.

 

i just replaced mine about a month ago. they were identical in every way

 

Thanks a lot guys. Appreciate it.

 

I just took a look at the metal mount brackets that bolt to the engine and they both say 14037877


So I have 2 right side brackets?
These weren't from my car, they were on a 70's 350 block.
I got these two brackets two fit in the car last time..I'm confused.

 

i could be wrong, but i think that gm used the same style mounts for a lot of different vehicals with small blocks.

 

I was under the impression that the early '80s Monte Carlo used the exact same 305 mounting as the third gen Camaro. It seems plausible.
But when I ordered my Moroso mounts on Monday, I noticed they listed different part numbers for the late '70s Camaro than for the mid '80s Camaro.

 

any one know which is left and right on the engine block

 

Here is a picture of the engine " clamshell " brackets,........
