ADDCO Rear Sway Bar 3/4” or 7/8” Diameter?

I'll ask, since nobody else has, what leaf-spring set are You running? If You get too stiff in the rear vs frt., it's gonna be tail-happy, & old worn eye bushings can make it dangerously worse. Steering the car around while You feel like You have to chase it, not enjoyable. Some have success racing w/o them with the frt bar & the right T-bar/leaf balance. I've run 1.25"/.75" combo w/.870 bars & stk leaves with 2 added to each stack. Very comfortable & competent.
