I SAW THAT FIRST USED ON 1933 Chevrolet roadster owned by gene vrendenburg a member of the L A Roadsters. Car was on the cover of rod action magazine in late 70"s
??
I believe he had it mounted using oilite bearing , pillow blocks, mounted to the bottom of the frame. SCHROEDER custom makes sway bars any width you need and aluminum splined arms. This is for the 7/8" splined ends type. I have this on the rear of my jag suspended 35 chev coupe and my under construction 35 chev roadster. I am using .800 thick and .850 thick bars. Really stiffens the ride but tell you this, your quarter panels in back will never touch the tires even with only 1" clearance. There is no more body lean. !!!! the rub rub rub is lone gone.
I have a couple pairs of 8 1/2" long C to C nascar prepped aluminum arms for sale
