Help with a measurement please

[ryanroo]

I am getting ready to install the gooseneck turnover ball hitch in my frame and i need a bit of help. i think that i remember the wood bed was all but right on top of the frame rails at the kick up above the rear axle but i don't know how far above the frame the metal floor is.

Can anyone with a steel floor bed pull a quick measurement from the top lip of the frame rail to the lowest part of the bed floor ribbing?

Thanks

My K20 has a crossmember directly over the highest part of the frame. The bed sits on top of the crossmember, and there's some sort of plastic (nylon?) spacer between the crossmember and the frame.

The gap from the top lip of the frame rail to the lowest part of the bed floor ribbing is just under 1".
