Hey guys, Any updates to this post? I have a 1978 280Z coupe with factory A/C - i brought it into the shop today and found out that it has NO heater control valve at all - so getting it refurbished is out of the question. Black Dragon Automotive, The Z Store, ect are still not able to find a distributor. Any way around this / is there anyone on here that has one that they are willing to part with? Thanks!
