Sway Bar yes or no

abodyjoe how much tire clearance do you have with the 1 1/8 5906 hellwig?
You think the 1 1/4 5907 hollow would be to much and further cut tire clearance. I’m planning on putting 17s on my 68 barracuda and already got 73 up disc kit. In input would be great ! Thanks
calipers are to the rear and i have no clearance issues.

@72bluNblu would be better help with the other questions.
