Our subject is a 1962 F-100, that will be running in both E/PP and C/PP classes. Part of my task list is to install outriggers, for lack of a better term, on the sides of the frame rails for the roll cage to mount and/or weld to.
It seems that most of the discussion, and specific criteria given on the subject refer to unitized construction vehicles. My question has multiple parts:
1. Is theres a minimum/maximum allowable pad area for the cage to mount to?
2. Can the down tube be welded to a flange that is bolted to this outrigger?
3. Is there a minimum/maximum allowable distance required from the edge of the frame section for the cage to be welded/mounted?
4. Does the frame (factory open "C" channel) require boxing plates at locations receiving these mounts?
My initial plan is to weld formed 1/4" steel angles (with welded 1/4" gussets) to the side of the frame at all locations requiring down tubes. I plan to allow for a 6" x 6" horizontal surface for the cage fabricator/installer to work with. I had also considered machining holes on the vertical plane of the angle to allow for more weld area, if required or advantageous for strength.
Thanks for the advice!
