1961 Lancer

1. easiest Sanden compressor mount seems to be modifying an original Slant Six bracket from an original A/C A-body
2. remove the heater/box system from the firewall and fab a cover plate for the hole
3. install a pusher fan in front of the condenser behind the grill
4. install a combo Air/Heat under dash unit and use as big of a unit as possible. The one shown in my 4 door Lancer has marginal output on a 100 degree day.
5. swap the stock alternator for at least a 60w
6. do not overfill the system with refrigerant trying to increase the cooling efficiency - it will only create excessive head pressure

hope this helps
