70 dart 470 ci drag car build.

As soon a I get the cage done I will be removing the factory floor pan from the firewall forward to just underneath the firewall rear. (backseat area)
I then will build a structure to tie the car together side to side and add in the additional rocker bars into the rollcage.
I'm going to use legal minimum.024 steel because I can weld that in, I was thinking aluminum but rivets are the deterrent.
The reason why I'm replacing the floor is because strength and the car isn't seeing a track this year and hurrying and quality (safety) don't go hand and hand.
