MSD Distributor Install

I have a 1968 440 in my 70 Duster.......I am upgrading the entire ignition system and I have a few questions on a installing a full MSD system.

MSD 6AL box
MSD 32739 wires
MSD 8202 coil
MSD Pro Billet 8546 distributor
Champion RJ12YC plugs

Tips or tricks on the distributor install? Never installed one on a 440 and its been a long long time since I last had to mess with one......

Where is the best place to mount the coil?

What gap should the plugs initially be set at?
