The engine mounts are the same but the frame mounts on the truck are different and you'll need to by a new set. When you buy them, they are going to look different from each other and they bolt right up to the trucks frame. I have the 4L60-E tranny and it bolted right up. If you have a 5spd you might to look around on the fourm to see if people had to make any changes.
