** The door and inside window trim have the same shape on the aft end thus the curved whiskers were used on my 52 five window & 53 Suburban on both sides of the glass and looks correct to me. The curved whisker would also be used on the outside of the window no matter what year. I'm also thinking the curved whisker would also look better on the inside of the window of all the trucks no matter the year due the fact that all the doors and window trim have the same shape on the aft end. I guess the best answer is it's your truck.
