Thanks so much for the input, and the kudos on the car!

I will check out the companies Ron suggested for roll cages and I will call our local race shop as well. If anyone needs any Javelin interior parts I do have that stuff for sale, you can find the post in the 'AMC for sale' section.

I'd like some additional advice because I have read so many different things online regarding nhra roll bar/cage rules. Am I correct that if the car is over 10 seconds a roll bar is ok, less than 10 a cage is required? I can't see the car going faster than low 11's with our combo, and I'd rather not add too much weight after carving so much weight out of the car. Then again being safe is smart, and I'd imagine a cage would further stiffen the car. Could a roll bar legally be converted into a cage if we ever go fast enough to need it?

Thanks again for all your help!
