Step notch for a '71, and keeping ladder bars

[smashingchuck]

Does anyone make a prefabbed step notch that follows the frame nicely for a 71? I need probably a 8" notch.

Also-
I would like to keep the ladder bars set up out back if possiable. I plan on boxing them and making new bag mounts out board of the originial coil location. I also think I may need to run a slight block. The question is, though - am I going to be able to make this work and lay out on a 295/30/22? Or am I going to have to get a four link instead. This truck is going to lay frame - I already have the front issues taken care of.
