Are you offsetting forward or rear? the main thing you have to look out for in the power steering box. Some mounts wont allow you to use the "truck" style accessory brackets, as the power steering pump will hit the power steering box. Also have to keep in mind the height of the trucks alt and intake and make sure you will have the right hood clearance. Here is a picture of how high my intake (stock truck) sticks up above the fenders of my monte carlo. I'm using BRP hotrods swap mounts.
