Re: Project Never Ends
Yes bars go through the floor. In the rear the bars go directly into the corner of the rear frame, tube actually laid up agaist the diagnol brace that is there. I then added some gussets from tube to frame.
For the main hoop goes through the floor, then I welded some 3" x 3/16" flat plate on each side from tube to frame, with one of the plates going at an angle into the body mount bracket. Was easy to do actually and very strong. To be NHRA legal it has to be attached to frame.
Now keep in mind for anybody considering a roll bar/cage etc. With the bars attached directly to the frame its like a big drum inside. Noise from my fuel pump, engine (solid mounts), you name it is brought directly inside the cab about 6" from your ear.
I do plan to add padding and wrap all the tubes at some point to help. But there are disadvantages to bars inside for sure.
