The requirements for bolting in a roll bar are top of the floor a 6X6 steel plate bolted through the floor to another 6X6 plate. The roll bar is welded to the plates. There are requirements for the bars that make a roll bar or cage up. There are ways to make some of the bars bolt together and there are specifacations for that like for a swing out side bar. One thing that NHRA kind of assumes is that you are working on a car. Trucks take a bit more work. You are going to need the bars going to the back. Regan asked about how fast you went. That will answer a lot of question on what you have to have along with what you may want to do above that to help the chassis work and to allow you to pass if you decide to go a bit faster.
