size for a front sway bar on a '65 289?...

-a. 1"

-b. 1-1/8"

 

I doubt you would be able to feel any difference between the two, but you know the saying...the bigger the better...

 

so there shouldnt be any fitment problems. right??

 

well from what i have heard is that the sway bars need to be used in conjunction with different springs i would do more research so you don't screw yourself and the quality of your ride

 

I have a 1 1/8 on mine, it was an snap to put on mounted to the stock locations with new hardware. Car drives real nice. I also put the 620 springs on at the same time. I can't really compare to what it was before since it was a I6 before with the V8 in it and worn out steering.
