Build custom rocksliders

Hello,

Does anyone already build their own custom rocksliders or is there a sticky or a thread to do that step by step?
I'd like to build mine for my 2008 access cab in aluminium or galvanized steel.

 

There are plenty of peeps that have built their own, some copying set designs while others just add a 2x2 to under the rockers.

I have NOT seen a step by step here at all. Quick google though got me at least one forum with good info:

Aluminum sliders?
