A Body Disc Brake Swap 101

Does the caliper go on the front or back of the spindle?
I use to put them on the front but now I always put them
on the back.I like the looks alot more and they work fine.
I use the rubber brake hose from a 73 and up B body

The 73+ disks had the caliper to the front. I have heard that with it mounted to the front on a 72 down car with a factory sway bar the caliper can it the sway bar at full lock. If you swap sides with the spindle so you can mount the caliper to the back you need to swap calipers side to side too or the bleeder winds up being lower than the hose and causes all kinds of bleeding issues.
