Mar-Ktech,
No doubt! I've had these for 4 years, and I didn't even notice the lack of holes until now. Unfortunately, I can't remember who I bought them from. I didn't know about your products at the time or I would have called you!

Bolting up the step boards helped a lot and the #1 measurement Eileen gave me helps as well. Thanks Eileen! Or is it Peter?

There is a bolt hole at the very rear and at the bottom of the bed side, (it's not on the diagram I drew) if I knew how far up from the bottom lip of the bed side, I'd be golden. Maybe a half inch or so...
