I'm not up on AMC, but if it's like a Chevy... TDC on the compression stroke is important, not just TDC. Dot to dot on the timing gears. Drop the distributor in and get the rotor pointed in the right area so you can match up the plug wires starting with #1. Chevy "should be" at about 1:00 if you are looking straight down at the rotor. It doesn't "really" matter as long as you have the rotor starting at #1 plug wire and the rest are in the correct order. I don't know the firing order of an AMC, but Chevy is 18436572. So you would start installing wires with #1 and go clockwise in order.
There's a million threads that get into more details out there if you google it. I'm sure you'd find something addressing AMC specifically. Good luck.
