MrDanB,
I must apologize. I read your profile and thought you had a '42 pickup, when in reality that is your cylinder index, (whatever that is).
After checking your previous posts, it appears you have a '57 pickup.
The page I linked does not have a diagram for that year, so it looks like I wasn't much help.
I know I have seen diagrams for your year truck...red58 probably has one for sure.
I will take my Prozac now and hope someone with some solid info pops in to save the day!
