i have read that if you look at the firewall there is actually one designed into it. I have also read that if the bar doesn't also tie into the firewall somehow it is not really as effective. I know petty's garage makes some (don't know if it ties into firewall). Mopar makes one that does tie into the firewall. I have seen ones on facebook that I'm going to assume are more for show than actual performance.
its definitely money but this Petty's one to me looks good and ties into the firewall https://pettys-garage.myshopify.com...tb-001-pettys-garage-double-strut-tower-brace
