Thanks for the connents guys, I dont have any of the old ones to line up, ill just have to measure and go from there.

Another question,

i have 4 total cross members, there is a long stretch above the axle where i dont have cross sills, but there are two holes in the bed strips one on either side of the frame hump. I see on mar-k that they have a reenforcemnt sill. Am i supposed to have them? Also not the very front one, but on the bed strips there is a hole like there should be another sill right there. is there or is there not supposed to be. Cant seem to really find any good pictures or info showing how it should be.

It is a 57 3600 3/4 ton
