Note: For Hatch Back Rear Door sizes, use full rear door column (Actual clearance will be 2" wider than double full rear door due to construction of door frame from square tubing rather than flamed tubing). 97 - 03 Body F-150 LB has a 84" long standard side door.
* T = Top Dimension, B = Bottom Dimension
** Subtract 2" from door opening width to allow for gas props
