Hi there. I am restoring a 1968 GMC. I have been looking for the correct color for the steering column. Some people say they were color matched with the body. My truck is white, so im kinda lost if i should use white or black. Another posibility is red, as the seats and panels. Another issue i need help with is the position of the square, blue "GM Mark Of Excellence" decal on the inside of the door. Somebody has a pic i can use as a reference? Thanks!
