Thanks for the referrals guys! I'm busy with another project right now that will take me well into the new year.
Interior cages are the hardest to build, and most expensive. So it is worth it to do it right the first time around. In the pictures in the link greg posted, the a pillar looks awful to me. Remember, every bend in a tube is a failure point waiting to happen. I would recommend pulling the dash and following the windshield. I don't know what's behind the dash so not sure if that's an option or not. I guess my thought is if you are building a rig that you feel needs a cage, then so will the next owner, and therefore would not want it removed. The best part of going behind the dash is knowing you will never hit your knees on it.
