CR-1 wide and roll cage

So I'm thinking about putting in some racing seats and a roll cage soon as my car is due for some mods. I want to get the Corbeau CR-1 wide seats, but I'm unsure as to whether or not they will fit with a roll cage. I was just wondering if anyone has had any experience with these seats and a cage. Also, does anyone know where that roll cage/bar from the yellow Ground Designs Cobra came from. It's the only one that I've seen that will work with a tonneau. Thanks in advance.

edit:
I meant to say a 6 or 8 point bar

Thanks for the advice. I was intending on welding the bar in, in the first place. I guess I should have put that in my first post. I'll probably end up going with a custom job now. THanks again.
