dumb brake question

Hi all,
I'm putting my suspension back together on my 72 swinger. I have the 73 disk brake conversion with the "slider" calipers. Can someone tell me while looking at the rotor, which side the caliper is supposed to mount on (front or back)? If anyone has a picture of this I would greatly appreciate it. I think I put my spindles on wrong.

Thanks,
Stu :scratch:
