custom A/c Installation on s13 ka?

[mkiv98]

I've decided that in order to make my car really enjoyable, I'd like to have air conditioning, which my car never came with.

How difficult/costly would this procedure be? Would I need all oem parts or is there an aftermarket option? If someone could direct me to a good article or DIY, it would be very much appreciated.

The car is fully prewired for A/C from the factory. Just source all the parts, install, and charge.

They don't make aftermarket kits anymore, they did when the car was new but I doubt you'll track one down 20 years later.
