I understand that body on frame cars require a NHRA certified 10 point roll cage to be attached to the frame (as opposed to unmodified unibody cars where a plate can be welded on). I also understand that if the frame rails exist within the footprint of the seat then outriggers or a sill plate/tube is required outside of the seat footprint so that the cage has somewhere to terminate to when passing through the floor of the body.
My question is: Is it allowable to have the cage removable along with the body from the vehicle frame? This could be done with bolting. Would this arrangement still be certifiable? Or does the inclusion of a cage eliminate the removability of the body for good? For reference I'm considering a 55' Chevy for this application (frame rails within the foot print of the front seats) and looking to eventually have a certified 10 point cage.
Also, I'm new here. Please let me know if this is not the best place to ask this question.
