Review on Enhanced Performance 4.3 Motor Mount for GM by Energy Suspension 3.1141R by Troy Tec

4 stars because they are very difficult to fit. The holes fit without play. This is a problem on a 29 year old truck as little clearance is required for installation. The back holes matched, so I installed the screws in the back instead of the front. And swearing a lot, and the man fiddled with the motor until I could hammer in the bolt. No big deal, the truck won't notice the difference in screw orientation. I will update in about a year.
