I went out to our warehouse to measure the Trailair Rota-Flex Pin Box, # LC328330, and found that the width is 12 inches. When measuring the length of a pin box, you want to find the distance from the center of the king pin to the bolt holes. The distance from the front row of bolt holes to the center of the king pin is 17-3/4 inches. The distance from the back row of bolt holes to the king pin is 25-5/8 inches. A few other measurements that you will want to consider are the bolt hole diameter, 5/8 of an inch, the horizontal distance between the bolt holes, 7-7/8 inches and the vertical distance between the bolt holes, 2 inches.

I attached a photo showing these dimensions for you to check out.

This pin box was designed to be an exact replacement for the Lippert 1621 and 1621HD OEM pin box. There should be a stamp or sticker on your current pin box that gives the manufacturer name and model number. If your pin box is not a Lippert 1621 or 1621HD pin box, or your measurements do not match, then send me your pin box name and model number or measurements. I will be happy to make a more specific pin box recommendation for you.
