Disc Brake Spindle Install

if you have a 73 and up style sway bar can you have the calipers mounted to the front?

Yup, that’s the way the factory did it. It’s just the 67-72 sway bar with the 73+ style brakes where you need to mount the calipers to the rear for sway bar clearance. Even then some people have mounted them to the front, but you have to shorten the end links if you do that and it’s tight.
