From what points on the running board are you measuring?

The pair of 3/4 ton boards that I have measure 72 inches along the top ridge just under the cab. If you do have 3/4 ton boards and they are in good shape you would be better off selling them to someone who needs them cuase they are to get hard to find and use that money to buy 1/2 ton boards

Here's a picture of the measured 3/4 ton boards
