Calipers contacting Sway bar

I'm piecing together my front suspension for a total swap out of the 68 6K, 9" drum setup. I have a 70 V8 K and the pre-73 LCA's with the sway bar mounts low. I am adding front discs from a 73 A body with the slider calipers. Pretty sure they are 11.75 rotors. 15" rims to fit also. My question is I see some discussion about calipers hitting sway bars and incompatibility problems doing this swap with the sway bar. Some put the rotor on the back and modify their brake lines. I need to know if with the equipment I have now, am I going to run into problems with the calipers and sway hitting and what can I do short of modifying the factory engineering to avoid this. Do I have to switch to a 73-up K with the sway through it? LCA's also? Thanks
