Yes I do, BUT,, that's also why I have to slow it down to 11.50 and slower. IT AIN'T NHRA LEGAL. You can see the rear bars going through the bed, into the back brace, instead of the main hoop,
in this picture
The ROLL
BAR OR A
CAGE cage MUST have the rear supports, the they MUST attach within 5" of the top of the main hoop, THE MAIN HOOP must be NO MORE THAN 6" above the drivers helmet.
You can put a secondary bar across the uprights 5" below the main hoop to attach to, OR you can bend the rear supports to come inside the cab (through the window) and then turn up the 6" to meet the main hoop.
Option is a funny car cage like Kevin's, I think you can get away without the rearward supports with that type of structure. But even then you will typically see the rear supports through the cab to make the structure rigid. At that level aesthetics are less important than safety!
Of all the welders, grinders, angle finders... the most important tool in building a cage or a bar is the
RULE BOOK. Seriously,, have the rule book in your left hand when your cutting tubing stock with the right. That NHRA rule book is a slippery slope.
