the east coast and the south) to the very first cars that came to the USA, as 
part of the whole recall/rebuild affair for the '71 cars.

>>>The registers are unobtanium, for the most part.   They have a nasty habit 
of breaking, and they were unique to the Pantera (I've heard that some 60s 
T-birds used one that was somewhat almost similar, but different).   Realize 
that there is a heater/air conditioning box behind the registers, with two holes 
cut in it, so in order for a third register to be effective, you'd have to 
pull the whole dash apart and cut a matching hole in the box, then equip it with 
proper foam sealer etc. etc.

There are a lot of things you can do to improve A/C performance more than 
adding another hole in the dash.   Colder air is better than more warm air.   And 
I've been in Panteras with stock A/C setups (other than a rotary compressor) 
that were uncomfortably cold with just two vents....

Mike (hoping to hook up his own A/C before long....)
