style/roll bar mounting points
I am looking at a homemade stylebar/cabin brace and was wondering about the design shown in this pic:
it appears (to me) that the bottom part of the brace is a big D shape which would give good support to the two bars that protrude backwards to brace on to.
the front of the support has 4 bolting points (two in the center and the seatbelt pillars) so what I am wondering is how is the back bolted?
are there mounting points for bolts hidden away there? I am a bit unsure of what areas are safe as the petrol tank is under the parcel shelf.

Roll bars
Mine are chrome and to my shock only mount at seatbelt anchor point. Bear in mind the wall thickness of the tube. This will be a big factor in the overall strength of the bar. I suspect mine could be a generic bar designe to fit various vehicles. They do however followcontour of seats. They have a large mounting plate at anchor point . The mounting plate overhangs seat belt anchor point quite a bit. My first thought when I saw it was that this plate was that size so as to fit a multitude of mounting points. I would attach a pic but that's another story. I really like the look of the chrome. Styley as.... I recall thinking that they looked like about 60% of my original purchase price. Helped clinch the sale I my mind.

Mandrel form bends or rolled bends have a much superior finish to them compared with a clamp formed bend....stops creasing at the beginning of the stretch point. Tighter the bend the more stretch.the excess has to go somewhere.... Life as an Industrial Electrician in previous jobs saw me working on many different industrial machines and processes....helped me get my Amateur Blow Arse. badge on the Scout Blanket also.

My GF was talking to her doc who rolled his MX5 and swears his roll bar (proper one not a style bar) saved his life she is getting insistent on wanting one. He put it upside down and the A pillars collapsed.
That pic above of the hoop style one looks like they have to keep the window zipped uo in the top? Isn't that a big no no?
Any way I'm going to go by some local cage builders and see about getting a proper twin hoop roll bar made up.

Roll bars
It's great how we read a comment and it gets us thinking or scuttling of to the man cave shed to check our own jalopies..... Is a style bar a particular brand or simply a reference to something put on mainly for aesthetics... I checked mine and it is not chrome but 50mm polished stainless judging by the size of the weld puddles. I'm not a metallurgist... They still look superb especially when the sun reflects off them. They anchor at the seatbelt points and brace back to the rear parcel tray with a couple of square blank plates. These are not bolted or drilled to anything.... Thinking now that I will investigate further to strengthen beneath them. At the very least it provides two dimensional bracing to the hoops over my scone which is a lot more reassuring than a single cluster of hoops. PM if you want to see mine MrGrey or others and I can email pics.

style bars are basically there only for aesthetics whilst roll bars serve an actual protective role.
basically, if its just loops with little bracing then its a stylebar while if it has bracing and mounts at triangular or square points on the horizontal plane then its a roll bar. (I hope that made sense)
to me, if the piping the the image I linked is thick (strong) piping and the welds are good strong welds then due to the 2 rear angled braces (which makes 4 attachment points on the horizontal plane) then it is a roll bar because it could help protect you if you roll the car while a style bar has the risk of acting like a mousetrap.
I don't really consider the image I linked as a 'true' rollbar because the 2 loops could potentially roll inwards and this bar attached to the pillars while the best rollbars (to my knowledge) are affixed to the floor.
