Rear sway bar with rear drop shackles on a 67?

[Russ.W.]

G'day all,

I have purchased rear leaf-spring drop shackles from ECE (1.5" drop using stick springs), and I'd like to also install a rear sway/stabilizer bar.

Does anybody know if the ride height change from the drop shackles interferes with installing a rear sway-bar from any of the aftermarket manufacturers? I understand rear sway-bar's weren't a factory option?

C10 is a 1967 2wd Shortbed.

Thanks for your time.
