If you guys want roll cages, I have a guy I sub contract out. He's probably the most talented fabricator I've ever seen. All work would be custom for your car and he could work it to your specs.
If anyone is interested get ahold of me and I can introduce you to him and his work. I've seen this guy build some incredible cars. He also rally races and builds full rally cars. Definately a wealth of knowledge can be had from him.
