Where are the cross sills located?

[lucusbumanlag]

I have a 1972 c10 stepside wood shortbed. I took off the bed from the frame to install new wood. I forgot to take picture of where the cross sills go on the bed. I dont want to put all the bolt in with the cross member, then it not lining up with the frame. Does anyone have pictures or can explain where the cross sill are located on the wood bed? Thank you.

Since your strips are probably prepunched this should be easy.
Measured from the centerline of the front stake pocket to the centerline of each crossmember, they are located as follows.
K=2.55"
L=13.92"
N=20.90"
S=59.66"
T=76.25"

The drawing is for all three bed lengths so don't worry about the extra stuff.
