Run what you want. I run the f250 towers and they work just fine.
Alot of people run them.
Hack the old shock mounts off and weld the new ones on.
Just make sure to brace the back side of the Ford shock mount.
Basically you could do this 2 ways
Put a peice of 2x2 sqaure tubing behind it flat on top the frame rail behind the ford shock mount weld it to the top frame rail and to the top of the shock mount.
Or cut 2 triangle peices of flatbar with a long arch to them weld those to the backside of the shock and top of the frame. Either way you are taking stress off the side of the frame rail.
