I have a 62 Mercury wrong bed short box and I’m thinking of putting a proper box on it. I have two 8 ft boxes that I could use to shorten and I have a mercury tailgate for it as well. I know this tailgate is for 67-68 Mercury, I have a 64-65 mercury tailgate as well. Just no pictures in my phone. Does anyone have the measurements to cut the 8ft box to sit on the frame properly. Is the wheel base different on the 61-63 short box trucks than the 64-65 trucks? Thanks. Doug.

Reason: More info
The difference between the earlier truck, 114” and the later 115” is the Twin I Beam front suspension. The bed dimensions behind the cab did not change so if you follow what I did it should be good to go.
