Re: welding roll bar plates (G-reX)
What exactly are you looking for? It is pretty simple...weld the plates directly under the tubes which come in contact with the floorboard. If need be, you can bend the plates as well, say for instance, up onto the rocker boxes or something similar.

G-reX,
In my experience, it would be best to use four points to mount the cage to the floor structure. To accomplish this, the best method I have found is a little more involved and using 1/8" thick plate isn't nearly enough thickness. What I have personally done is this, I cut a hole at each mounting point in the floor same size as your cage tubing. Now, get 8 sheets of 1/4" 6 X 6 steel. In four of these cut a hole dead center for your "A" and "B" pillar mounting points. Next raise the cage and slip one under each corner and let that plate slide up each bar in place. Next lower the cage through the four holes directly under each post and drop to the ground. You want to take the remaining 4 plates and weld these to the base of the cage now located under the vehicle. When done at all four corners raise the cage and drill four holes in each plate assembly including through the floor pan and using those 4 bolts, bolt each with at least 1/2" grade 8 bolts, nuts and washers. Now weld the top plate to the post on the inside of the vehicle at each corner. What you have done is sandwiched the cage base to the floor pan and it is not going anywhere anytime soon. Then if you choose one can go ahead and weld both the top and bottom plates to hte floor pan, although not necessary.
I've done this many times with excellent results, DAMHIKT.
A side note, I have seen cages that were just welded to the floor hap-hazardly fail during crashes.
First, you need to look at the rules of the sanctioning body you plan on racing in. That will be a good first step in this process. They will specifically state what to use and how.

Donnie</TD></TR></TABLE>that is a very, very smart way of doing it. the only thing i have a problem with is welding both plates after it is boted. see, once the plates are welded you pretty much just put a dotted line around the 2 so to rip out in a big accident.

Re: welding roll bar plates (archmage)
archmage,
Well, I don't know this gentleman (L-con1) but I have seen his work. He IS a master at building cars the way they should be. You know, as a matter of fact, I couldn't tell you much about him at all, except to say, he is the pro everyone on here NEEDS to listen to when he makes his comments. His experience is bar none the best and so are his fabs. You would find no better man for the job.
Hell, I live in Missouri and no where near this guy. I simply have viewed his work, reviewed his processes he has previously described and examined his thought processes about thoroughly building safe cages. Take a look at his website and you will get the picture of what he is capable of doing for you. Neat stuff he does.
Go to him and you'll have a cage I would without hesitation get into in a heart beat, because it will be done right, and done right the first time it is done. Then all ya gots to do, is go play and you'll be protected as well as one can be participating in the sport. If I remember correctly from a thread long time ago his name is Louie. Sorry L-CON1 if I am in error. I believe though it is correct, right?
JMHO
