My rubber adapter plate grommets are worn out causing extra shake in the motor hood-cowl housing. I purchased new ones, but can't figure out how to remove the old ones? I've removed the 4 adapter plate bolts, the cowl skirt for a better look at things, but getting under the adapter plate itself to access the grommet bushings Is looking like a major ordeal. Is there a trick to changing these out? Any help would be appreciated.
