I bought a deluxe T body from Speedway with a door. I cut the body for a 3 inch channel but the door sill ended up below the frame rail. I raised the body 1/2 inch to make the door sill even with the 1/2 floor. Is this a common problem or did I do something wrong? I think I can raise the body even 3/4 inch and still look channeled. Let me know what you think.
