Would like to know if anyone has ideas/pictures on routing the middle AC duct to the back for a rear ac duct?

You could run it through a console if you are installing a console. You could also have a false rise on your tunnel and hide it in there untill it gets under the seat. That's all for now.

That would all depend. As Josh said if you are installing a console run a duct under it and have it blow out the back end of the console. If you are going with a bench seat you would have to run a duct beside the trans tunnel since the seat will be close to the top of the tunnel.

I think that's a great idea Shawnmil, and one of the things I want to do on my nomad build (when I get going on it that is...:D)

If you have welding and fabrication skills, you could make a duct that would lay ontop of the center hump and hug it towards the back. Assuming you have bucket seats and a console in mind to cover it all up...

Anyone got some pics of that?

These tri-5's need cold air in the back too. :cool:

No pics, but if you look at most any van, mini van, Tahoe, Suburban, and the like, they have a/c and heater outlets placed well for passenger comfort.

I think that how you might route these is going to be dependent on what you have for seats and console. Consider that the side outlets for the a/c up front are just 2-1/2" round. You could make a rectangular duct of a similar size that's flat and wide.

The other thing to consider is a rear air unit like on Suburbans and big vans. You can run two evaporators from one compressor - the factory does. You could use a small universal unit from VA, etc. or even a factory unit. There's got to be lots of ways to mount that in a wagon. Or in the trunk of a regular car. In the 50s some of the Caddys and similar cars had the evaporator in the trunk behind the back seat. You could use dual air or a single unit and run the ducts forward. Lots of ways to do this, though some could get complicated quickly.

WOW.. That's cool.. No pun intended. :p

I have rear ducts on two of my cars and never thought about doing it to the '55.. that's until now.. :D

I can't wait to until I replace my suspension so I can install a sb v8 & 4 speed tranny so I can install a/c then run rear ducts. :D

Boy, this can get expensive.. and I thought off-roading was expensive.. :cool:

Vintage air hangs low :(

Not planning on going with buckets... I like the bench seat up front. So will have to figure out a way to run beside the tran tunnel or get a new evap for the trunk. Speaking of the evaporator. I just installed my vintage air under the dash and I am disappointed at how far it sticks down under the dash? Anyone do anything about this?

Shawn from what i have seen and read they are all going to stick below the dash somewhat. Some have built lower dash covers to help hide it and to give a cleaner look.

The Vintage Air Kit is definately the kit that is the MOST hidden & cleanest look.
From my research, the Classic Air & Hot Rod Air kits hang down below the dash much further than the Vintage Air Kits.
Please, somebody correct me if I'm wrong. I've been researching this before I buy a kit for my '57 2dr wagon.

I was planning on buying one of those clip on fans that you plug into the lighter to get the cool air to move to the back. My car is a driver though & not a show car. ( & I'm cheap )

Great Post too! One of the reasons I bought a wagon rather than a car was so my dogs could come along on cruises. Gotta keep the puppies cool too!:cool:
