Aftermarket A/C

[VegasCharger]

I'm in search for a '1986 to '90 Dodge Ram and I'd like to widen my search results by looking at trucks that doesn't have factory A/C because I want A/C and if a good truck comes along w/o AC I'd like to know if there are any aftermarket options to install A/C? I've done some online research but I couldn't find any solid information. Any help or tips would be greatly appreciated.

Thanks

I'm adding the factory ac stuff to my 85 as we speak.
