Are you looking for an anti-sway bar? They are designed for VWs - so pan based cars. Not sure if they will clear the Beck frame with welded on H-beam. I know on my pan based CMC I had to cut and reweld my front bumper brackets. Photos show how close it is to H-beam and battery box. I modified the bumper brackets to clear. My anti-sway bar is an ADDCO 3/4" bar. Carey can probably advise if this type bar will fit and clear. It looks like it would be close. Maybe try a stock VW bug anti-sway bar first.
There are some for lowered cars with slightly different profile. Some have also mounted them upside down - which could cause low road clearance.
