8 point roll bar

I'm more looking to see where the man hoop comes down and other people's a bodies and how they weld the main hoop to the floor? Where are they welded their back bars eventually too, near the back fender wells? And where's the bar eventually goes to on the front floorboard passing the driver? I do get I'll have to adjust the bar at the hoop higher or lower to go pass between my shoulder and elbow. I read the NHRA rules plenty of times and they don't need to be reposted like I'm stupid , I'm just dumb - I don't know :D a picture is worth a thousand words sometimes. But again no big deal I'll just do the best I can and post what I've done.
Have looked a lot on the internet and there's all kinds of cars out there but I'm just looking specifically how it goes into an a body.... thank you for any and all pictures and help as always......

the shoulder elbow thing is kinda generic. you can get that part right, and still have it go farther "or less" forward, depending on your willingness to crawl over it. that being said, farther forward will prob. make the car a little stiffer. I swept mine down sharper so my old but could get in - out easier. didn`t want the swing out kit, even tho I bought it before hand.
