Can anyone find me a great website where I can have all truck bed measurement for inside width (front and rear) and inside length of the pick up bed? I would need every year from first year the "pick-up" truck was born. 1947? maybe? to 2008. I have tried to call Ford, Dodge, and Chevy in Detroit and no one understood what I am talking about.

Please Advise!

Thanks!
