New Hellwig 55917 Front Sway Bar

I have a '68 FB FS with 11.75" rotors and pin-type calipers. I had to mount towards rear to clear swaybar (1 1/8" Helwig with straight arms). Will this bar clear large brakes mounted forward? Any thoughts would help.

It's designed for rim/tire clearance when using 16",17" or 18" rims with over 4 1/2" backspacing. Or 245 or wider tires with 4 1/2" backspacing 15" rims
