Locating the hump

Thanks for the replies, I guess I should have mentioned that I wont have the engine/transmission in the car. We are in the body/sheet metal phase and I was going to get all the welding done at the same time. It sounds like it will follow the original tunnel form so I will try it when I actually get the part...next week or so. I was hoping for a picture which would give me a visual reference cuz I dont think there is alot of leeway for positioning and still be able to shift properly. Mike
