89 f800 broken gas pedal

I recently bought a 1989 f800 single axle dump truck with a 7.8 diesel and 5 speed...but when I bought it the gas pedal was rusted and the hinge on the bottom of it broke off. I believe I have found a replacement pedal for it but it just seems like something else is missing from the throttle linkage? Does any one have some pictures on the throttle linkage on one of these truck? I would really appreciate the help guys
Thanks
