Core Support Brace

[451 Big Block]

I notice that a core support brace is offered for 71 & 72 Chargers. I have a 1974 Charger that I drag race . I'm thinking I'd like to stiffen up the core support and I'm looking for a brace to weld on while I am replacing the radiator. First, does anybody know if there is a company that specifically offers a core support brace for a 74 Charger. Or, is the core support the same from 71 - 74?

I was looking at these for my 74 roadrunner and got to thinking I could make one rather easy. It just seems like u channel across the bottom. Nice charger by the way
