JMO the pad seemed thinner than the repo I used 10 years ago. The cut out for the heater box covered the exit for the heater core tubes, I had to trim that. Definitely not what I expected. The impression I got from the Camaro outlet I purchased from was the manufacturer is aiming for customers to modifying the part for their application. I would have returned it, but had already cut the pad for the booster assembly. Now that it's installed nobody will know, but my expectation was slap it up and bolt it together.
