I've done something similar to my '84. No additional condensers or vents, but upgraded hoses, front condenser and evaporator. Stock fans. Works well enough to keep the cabin quite comfortable in temps around 95-100°F. If you are doing the work yourself, I'd budget around $2000 including hoses. There are some people who say hoses are not necessary, but they are ~30 years old by now, so why not do it right. Additional bits like replacement/upgraded compressor (if needed) or new fan blowers could bring that cost up to perhaps as much as $3000 in parts.
