I agree Tony, but I wish there was an in between size available to us, 1/2" too small, 7/8" to large. In the NPD catalog, I notice that they list an ADDCO 3/4" rear sway bar #5A772-3A for 71-73's and a 2 position adjustable #5A772-1B (whatever that is), and it states to match a 1" front bar with a 3/4" rear bar, or a 1 1/8" front bar with a 7/8" rear for neutral handling, BUT then it lists #5A772-10A as a 7/8" OE style (which we now know is not) replacement, must be used if the car originally had a rear bar......
So, if ADDCO make a 3/4" bar, will it fit a car that had original rear sway bar or not? OR is it a retro fit that needs different mounts?
Hellwig list a 1" front and a 1 1/8", w/factory rear sway bar #5482-7D. They do not list rears for 71-73's
So from that one would have a 1 1/8" front with a 1/2" rear, Hmmmm!
The debate continues.
