My friend was killed, driving his car on the street. It had an 8.50 cage, and had a "helmet" bar . He got T boned making a turn and hit his head on the bar. He died a few days after the accident in the hospital.
Please if you have a cage, make sure it has padding , and even better wear a bicycle helmet at the minimum when riding in the car on the street. ANY accident with no helmet will be very bad.
ANY one riding in the back seat of a car with a roll cage/bar will definitely get hurt without head protection. Keep that in mind please
X2 It's without a doubt less safe without a helmet, it has to be a risk you're willing to take. If I ever put a rollbar in my car I'm not letting anyone ride in the backseat anymore. The headrest that GY3 installed in his '63 is a nice solution too, definitely adds safety on the street.

That's pretty good. Can't say I have seen a headrest put in like that before. I stole some of the basic design elements from Tim McAmis's shop. We designed the pad to emulate the contour of the main hoop. I didn't care for a round pad. I can explain to my neighbor Dave what I want and he makes it happen!

Hook up with the NHRA Chassie Roll Bar person and have him come over to look at the car. Dont paint until you talk to this person. Bars needs plates to be welded to and the plates need to be welded to the car.These places are 6 inches of flat surface. Also one other car we race has a side swing out and has a 850 tag and goes 880s. This car is a Joe Smith Built car so it passes tech with flying colors, and every NHRA tech guy reconizes his work. If you plan on only racing your car a few times at the track all this work could be for not much. You can always rent the track with friends and have fun testing without to many eyeing your times after each pass.

6" plates.
I had initially thought about doing my own bar but, in the end, the experience and reasonably cheap price quoted by the local race shop sealed the deal for me. They thought of things I hadn't.

Last I checked plates can be bolted
Back when I raced my Challenger on the weekends my roll bar had 6 inch plates that were bolted to the floor both on the Side bar, main loop and back bars, with plates on both sides. The Cuda we are building the plates are welded to the floor close to the side and are not flat but follow the angle of the floor to get the Loop wide in the car to make side bars easier to locate with Door Panels. The 6 inch plates do not have to be flat but must be at least 6 inches. When we started to look at the today rules it was hard finding information on roll bars. When the Chassis Cert guy came over to do a 850 tag on another Car a 1965, we questioned him a ton of what is legal. There are kits for sale that are pretty good almost bolt ins but the Cuda we are building the Chassis is super stiff with us building the Roll Bar and frame connectors the way we did. Only the first few passes will tell us how well we did but when you have a Template sitting next to the Cuda it makes it easier to copy a lot of things.

You never want to be in a situation to test out a roll cage! Make it the best you can.

Absolutely make it the best you can with todays technology. Back in 1973 my Challenger ran high nines and that was with a crap roll cage with no side bars. They were the rules. As things began to happen with safety and back then there was very little when it comes to safety or even chassis technology things finally started to change. My Challenger did not even have frame connectors. Like said by Cudaman 1969, you do not want to test out your roll cage. The Cuda we are building has all the safety technology that 2023 can give to a car. Old crap roll bar is gone, old crap frame connectors are gone, Cuda ran 930s in 1972 in Pro Stock and even faster in C/Altered in 73 74 75 and the owner wants to be safe having another car that runs 8.90s and rides the rear wheels well into secod gear, correction via Cab.

I will change that for you Cab and type what wheels. Another buddy kind of rode his front wheels with his front wheel drive Neon, with a 13 foot wheelie bar running 7.90s. This 65 Bel rides a giant wheel stand and your right on the back wheels well into second gear with the automatic. Foot Brakes the car.

AJ's team at Bob George Racing did my chromoly cage for my 71. Tucked in around my door panels and through the package tray right on top of the frame. I wanted it sleek and tight to the body and they delivered. If you're spending big money regardless do it right. Buy once cry once. I opted not for a removable cross bar, e body seats are useless as is so it wasn't worth it for me.
One thing that's an absolute, you need padding on these cages especially for the street or else come accident time they become a weapon as you bang around in your seat without a helmet.

Your cage looks very nice and well built. But I have one critique that is not directed towards you because it's not easily changed, but for those designing theirs in the future, I'll share my comment.
It mainly concerns the two lower main hoop braces. They "look" perfectly fine and normal as installed, but unless there is some structure unseen in the DS tunnel that ties the lower ends of the braces to each other, it's not a solution I would suggest. IMO it would have been better to connect both lower ends together on top of the DS tunnel with a single formed 6"(?) sq mounting plate, ie a single node point. Every solution has a downside, and the only one I see with this suggestion is a shallower angle for the braces, which IMO would not outweigh the stiffness gained from this change.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I see what you are talking about jcc. On the Cuda we are building the bars are much lower and attach to the frame connectors through the floor, that are also round tub. Connectors join up with the rear frame at the back and the run through the Transmission cross member and up to near the fire wall and to the front frame. He could have a ladder bar mount in the position of his bars or not. On the Cuda we are doing it also has an anti sway bar that runs from one frame rail to the other and has other support pieces.

Pretty car, looks like two different blues? in door and out door lighting. Did the same to my car before I seen it. Enjoying the post, thanks again for the ideas.
