Is this new condencer a stock replacement? favoring the R12? or is this for someone like me... who has switched over to R134A? My 72 is converted and i DO plan on adjusting the poa valve down to 26 pounds for r134 from 29 for r12 but I have a stock condencer and all the pros recommend useing a parallel flow unit to get the most out of the stock system even as ineficient as it is. Does anyone make a DIRECT replacement parallel flow designed for r134 for 68/72 corvettes? 
Thanx......Hammadown

They are a direct replacement but I wouldn't say they favor any refrigerant. Both types would work fine.

Thanx for the reply
but if this is an EXACT duplicate condencer as the 68/82 then I think it still favors the R12 refrigerant
A "parallel flow" condencer is designed to work BEST with r134a and thats what I am looking for. Does anyone make a DIRECT REPLACEMENT parallel flow condencer for 68/82 C3's ???? according to all the ac experts a parallel condencer would optimize the conversion to r134a verses useing the STOCK r12 condencer ! also..... considering that r12 is "yesterdays" refrigerant and getting harder to find and is VERY expensive compared to r134a , would you or could you, consider designing and building a parrellel flow condencer as a DIRECT replacement to the stock 68/82 r12 condencer?? to optimize the r134a conversion along with dropping the poa valve down to 26 lb's for r134a from 29 lb's for r12 !!

I have the stock setup that is converted to r134a and it blows cold but Im hopeing to get it colder once I adjust the POA valve down to 26 LB's ! but I feel ......along with the pros..... that a parellel flow condencer would be "THE ICEING ON THE CAKE" for a r134a conversion

Merry Christmas Tom!
Will one for the 68 ever be available? And how about all those unique 68 aluminum a/c fitting/tubes?
Thanks,
Bryan
ps What would it take for you to re-core my original 1972 LT-1 with a/c radiator?

Same thing
You can buy the core and have a local rad shop do it
As far as the Parallel flow models go, yes they are more effective with the newer refrig. but we didn't make them as an upgrade, just a replacement. There are companys that make the parallel universals if you wanted to convert the mountings and fittings.

Thanx for the reply........... Thats just it..... I would want a direct replacement I would NOT want to mess with mountings and fittings I WANT a DIRECT and EXACT parallel flow replacement
remove and replace.... clean and simple
and I think with all the corvettes that are still around (68/82) that have converted the refrigerant would be interested in a unit like that I think there is a market for a unit like that ...and I would be the FIRST person in line for that unit
Thanx Hammadown

My uncles bodyshop vacumed out the r12 and converted over to r134a with their machine, the center vent got to 34 degrees ...in the shop,90 degrees 12 inch fan blowing across the condencer. I asked about the oil and he said the old is sucked out and the new goes in all automaticaly this machine does all cars makes and models. I also changed the drier and put a new hose on the compresser . worked good till I pulled the suspention and YANKED the motor

Sorry......... i think I meant to say 38 degrees or 43 degrees
either way.... that was without direct sunlight on the car and a fairly cool, cooling system. the car was unstarted for 6 hours while we did the conversion...so I think that temp was the best I would see Now add the august sun and hot temps and regular city traffic and the system gets less eficient 
Not to mention the poor air flow (or) reduced air flow from the stock blower motor change the pressure from 29lb's to 26lb's on the poa and add a NEW parellel flow condenser, DIRECT FIT,replacement and the system should be ideal whatever ideal would mean for a 68/82 C3 ac system

Tom, you should contact some of the after market AC people like Vintage, Classic, Hot Rod Air, etc. Their condensers can be made to fit, but are not the nice replacement style like you offer. A direct fit parallel flow should have some good sales potential.

Tom ......... I think it would be a great piece to produce and there would be many people who would be interested in that unit
and yes.........you could say its a vette thing.
fighting engine heat and exhaust heat and an under sized blower motor in our c3's makes the system work that much harder and any component of this system that can be made to be more efficient and work better is a plus for cooling off in the dead heat of summer
So.......... yes you can say that it's a VETTE THING
