Interest in Roll Bar/Cage Kits?

There are MANY cars running with "kits" that are certified. Most of them fit like ****...I'll say that, but they do pass tech/certification. I can do them for the Dart's no problem. The Duster's are probably fairly close, and if not, it only takes someone about 5 minutes worth of measuring to give me the dimensions I need. I plug them into my program, and start bending. The bending part will not be a problem...problem will be whether people are willing to pay extra for something that fits and looks much better.
