Does not fit gmt400 trucks even though their vehicle fitment says it does. These are larger than the clamshell itself and over an inch longer than factory mounts.

Fairly easy to install and eliminated the vibration I was feeling.

These motor mounts are high quality, but they did not fit my 1988 Blazer with the 350 (5.7). The product was listed to fit, but I had to modify them quite a bit to fit in the original clamshells.Other than that, they are 100% better than the old rubber from the factory.
