67 stepside rear bumper help please

[brian26]

I am befuddled as to how I need to get my rear bumper mounted onto the stepside.
I have the rear brackets, yet I'll need to drill the holes. And mount the gravel guards. This truck HAD the 'farmers- aftermarket- tank heavy' bumper.

For some reason, I find myself trying to make this complicated. Anybody got any detailed pics of how it should look underneath and from behind? Really need to know where to exactly drill the holes.


Thank you
