I am installing a Vintage Air Gen IV system in my 56 2 dr sedan. I have a BeCool crossflow radiator that I installed a few years back. Now I have installed the matching BeCool condensor.
I am trying to figure out the routing of the lines through the radiator panel, and where to mount the dryer, etc.
The Vintage Air liquid hard line that runs from the evporator to the dryer will place the dryer in a place that I can mount it due to the BeCool install.
Does anyone have this combination? Could you please post a couple pictures of how you ended up routing you lines and where you mounted the dryer?
Any help will be appreciated.

I installed a VA unit on my 56 Bel Air 2 door post car. It was an original six cylinder car and I left the radiator in the six cylinder position. I used the template that VA supplied to run the lines through the core support and had no problems. What position is your radiator in? Will moving it the six cylinder position solve your problem?

Thanks for the reply Tri-Five. My radiator is a BeCool crossflow which mounts in the six cylinder position, in front of the radiator support. With a stock type radiator Vintage Air provides a template for the holes, and all hoses are assembled. However, they do not provide any type of template for a crossflow radiator upgrade.
Here is what my system looks like, except I do not have the fans on the back of the radiator, or the extra coolant catch tanks on each side in front.
You can see where they route the lines. I am hoping that someone that is using this setup will post a couple pictures showing how they routed the a/c lines and where they mounted the dryer.
I know a lot of guys have discussed hiding the a/c lines, etc. I am not doing that. I just want them inside the enginer compartment.
Thanks everyone, Keith

Many years ago now, I put a polished PRC unit in my 57 wagon, and went to plumb in the condensor-dryer lines and figured out that without having custom lines made up to a certain lenght, I'd have to use what came with the kit.
So what you see is me figuring out to put the dryer on the frontside of the radiator mount.
Not perfect by Riddler Award build standards, but fully functional and has worked well for years now.

To me, the dryer should always be in the front where the coolest air is. It is also the liquid receiver.

I ended up using aeroquip lines.

Thank you very much gentlemen. I appreciate you both taking the time to upload pictures for me.
I do not have any problem with mounting the dryer in the front. It will allow me to place the panel hole higher where it is easier to drill. 
I guess I will have to get everything installed where I want it, then take it to the a/c shop and have a solid liquid line custom made to fit.
I must admit though that the custom aero lines are an interesting idea.

Thing is, cooling the liquid discharge from the compressor is the condenser's job, and obviously it is in the airflow. The drier's construction (no fins/tubes) isn't going to let it cool the liquid much if any even if it's in the airflow. To me, you should just mount the drier in a convenient place.

Agreed, the system will work O.K. with the dryer ahead of or behind the rad. And indeed, behind the rad. is where I've always seen it on OEM installs. But, just as evaps & their control valves are designed to work best with some 'superheat' at the discharge, most agree that a system is most efficient when the liquid output has a few degrees of 'subcooling'. So that, as it travels to the expansion device, it doesn't pick up enough heat to flash back to vapor again.
Again, not necessary, but given a choice, I like to get all the cooling help I can.
Maybe its from too many years of slow moving ag. & const. equip in the desert heat.

"Maybe its from too many years of slow moving ag. & const. equip in the desert heat."
Been there and done that on some oil exploration vehicles. We had to build "roof scoops" on vehicles that had a roof mount a/c - seems that without that, they were recycling their own hot air off the condenser when still or near still. It made a huge difference. Otherwise the hot air just moved in a circle and right back into the condenser fan intake. Before we built the permanent sheet metal fix, you could hold a piece of cardboard over the roof unit, tilt it vertical or horizontal, and watch the high pressure more 50-75 psi.
I learned a lot about a/c trying to make it work on those vehicles.
But again, the key is making the condenser work correctly. You need a big enough condenser and proper airflow (fan(s)).
