Roll Cage Design Does anyone have a good roll cage design or know where i could find one. I will be making a roll cage out of chrome moly. Taking the back seat out isn't a problem. But I would like to keep all other interior parts in if possible. Thankz for any input.

No, my car is pretty much stock. I go to Wyotech and I can get all the chrom moly I need for around $150 since my school buys it in such high quanity. Im in a fabrication class right now and wanted to use my car as a project. So I either need some nice pics, blue prints, or just go at it with a measuring tape and welder

You should also review various sanctioning bodies' roll bar requirements to see what they call for. Most of them will have the same or similar requirements, but there may be some significant differences as well (particularly depending on a car's classification). My point is if you're looking to become a chassis builder you will need to know what the various requirements are. So you may want to review those rules so you can build a cage/roll bar that will be safe, pass tech, and provide improved chassis rigidity.
you can end up with a bunch of junk in the car if the chro-mo isn't welded correctly. Also another vote for looking at sanctioning bodies, SCCA, NASA, NHRA have different requirements depending on what you're doing.

If you are going to WYO tech then why not just sit in the car and imagine what you can do. If you cant see the finished product in your head then dont start. Creativity is what makes you good in this business. Being able to copy a design is easy. Its coming up with new ideas that is the hard part.

Like has been said, check out the rules in whatever racing you want to do.
That said, be sure to note the differences between drag race and road race cages. A drag cage gives equal protection to the driver and passenger. A road race cage gives much better protection to the driver. Basically, the main difference is that a drag cage has a continuous horizontal brace on the main hoop, then 2 additional braces that go from the horizontal bar to the floor (though why you'd want to brace the horizontal bar vertically is beyond me). A road race cage has a continuous diagonal brace running from passenger floor to driver's head in the main hoop. Then, the horizontal brace is welded (in 2 pieces) to that brace.
