How do I install a LA distributor in a Magnum?

I’m working on putting my motor together etc... before I drop the motor in the truck I would like to put the LA distributor in the 5.9 magnum. I’m running a carb etc... I’ve never really have messed with a distributor before so I’m assuming I need to bring number one up on the compression stroke? Then set the distributor? Do I need to pull the distributor gear? Also where should the rotor point? Basically I need all the info I can get on this!! Thanks
