That is a "bolt in" cage, so its design will be different. It also doesn't attach to the firewall, a-pillars, B-pillars, etc. A weld in cage is really the best way to go. The door bars need to be plated to keep them from seperating and I am not a huge fan of the weird connection pillar to the floor. Should have run those bars out to the rockers and attached there for better strength.
