1974 D100 frame off build up

An SRT Brembo would look great. Challengers are 4,200 lbs and a short bed D100 is just 3,000 lbs. It would keep it n the Mopar family too.

My main concern is the lack of aftermarket upper control arms. I have a 73 D100 and need to freshen it up with van lowers and a custom upper control arm. Bigger sway bar would be nice. I’ve been told a certain C/10 bar works?
