Re: what size motor mount shims needed?
As they came from the factory, shimming the motor mounts was not required.. Either those poly mounts are incorrect, or something is amiss with the frame brackets.. What are you referencing to determine correct engine height??

I have never needed shims. Pics are definitely needed...
