.100 mild steel chassis update
I have a 68 COrvette that is a round tube car at .100 thick tubing. I must tear into this thing (very deep) to update to get certified. I do understand that there are concerned about the driver area. I must replace the main hoop and the halo and the x braces in the doors and the cross bar under the dash. My quiestion is that the place where the main hoop lands is actually the crossmember, and it is .100 mild steel. The down bars on the front land on the same .100 mild steel. The rocker bar is also .100 mild steel. I assume the main frame rails are the same. Is there going to be a problem with the NHRA with joining the chrome moly to the mild steel and will I have to change the crossmember?? How deep does it have to go. The driver position is also behind the main hoop. Any info about the funny cage for that?? Thanks!
