How difficult is it to add A/C to a 68' or '69 that didn't have factory A/C? Is there a company that specializes in this. The ones I found do not have a kit for the GTO.
It can be done but you will need a "donor" car. The firewall section is different and will have to be cut and welded in. The other choice is an aftermarket unit by companies like Vintage Air etc. Look in the street rod mags for manufacturers.
