Hiding A/C Lines?

I am starting to order AC parts for my 56 and would love to pick your brain.

I looked into the vintage air kit, but wasnt happy with the controls, and exit of the plumbing.

I am going with vintage air condensor, as it seems to have a better mounting system, and then going with restomod air for the actual blower unit as its smaller, and will allow me to hide the lines better, and Fat fendor garage dash valence to mount controls and vents.

Question, has anyone ran the AC lines down the inside of the fender to hide them more? If so do you have pictures? I dont plan on running a heater, and dont like the idea of having the bulkhead right in the middle of my firewall.

I would also love to hear any insight or issues you gus may of ran into while installing AC in your f100s. I have only done this once before in a 95 f100 that was full caged for offroad. Its been a few years.

I think a few guys here have ran them behind the passenger side inner fender and into the right side footwell of the cab. It's been awhile and I can't remember the specific truck (or person) but I think I remember reading about it.

I think the hardest part of it would be the connections at the evaporator box under the dash as most of them are geared towards the lines penetrating the firewall.

Good luck
Bobby

You could do it I guess. Not sure how mixing and matching different brands will work for you. I wanted to do what you are thinking about but using Vintage Air complete. I talked to a sales rep about it. They don't recommend doing it that was as there are more fittings involved so more prone to leaking. I went with the sure fit kit and bought a different controller, dash vents and chrome compressor. System works great. Just live with seeing all the hoses for AC and heater.

I am pretty sure restromod air unit has fittings that come out the side and was a bit smaller than vintage air.

I would love to see pics of your vents and controls if you have one. Always trying to get ideas. How do you like your kit? truck stay cool?

Also i thought i would drop some pictures i found yesterday.

The system works amazing. My problem is that the door seals, well don't seal. I will get new ones once I paint the truck. When sitting at a light the truck can get cold. Once driving the air coming in over rides the AC. Most of the time I don't use it anyway. Maybe a couple of times a year just to exercise the system.
If you want pictures from another angle, I would have to get them. This is what I have found.

If you dont mind me asking, where did you get that dash extension piece? I ordered a fiberglass one from Fat Fender Garage as it was the only thing i could really find. However yours appears to be metal and much nicer.

Thanks
I had bought a fiberglass one from Mid Fifty but it sucked big time. Sent pictures and many calls later they gave me back my money and I tossed it.
That one I built out of metal, ,either 14 or 16 ga. Picked a size I wanted and bent it into a U on a large brake. Made it in 2 pieces as the metal was only 4 feet wide. The fiberglass unit had a cutout for the steering and a recess for the glove box. Did not really like that recess so I made it the way you see it now. But now I need to figure out how to mount the glove box door to work. Really happy with the way it is looking though.

You could do what I did Marten..

welding a piece of 1/8 X3/8" flat bar to the bottom inside of the
door and then a piano hinge to it flush to the bottom..
Will be using pop rivets to mount it to the dash. The original hinges can't be used any longer so with the template I kept from my last build
I cut out new stays to support the door at the level position..

Did this first on my pickup and some explanation on post# 15 https://www.ford-trucks.com/forums/1...l#post15201350

I was trying to do that but can't figure out how to line up the hinge and mark/drill the holes when the door is closed.

Hi hxckidd,

I ran my ac lines inside the inner fender. The extra work was worth it for me to achieve the clean look. VintageAir components were used, plus bulkhead connectors from others, mostly sourced on Summit Racing. The remote condenser is mounted under the bed. Sourced from Southern Air/Hot Rods.

Lines going through cowl leading to VintageAir unit. Horizontal lines going to the right go to the remote condenser mounted under the bed.

John, we drive it weekly and other times as the fancy hits me. It's been fully finished only since April so I'm still learning it's quirks. Longest trip was to Sedona, only 20 miles each way. But when it cools off we'll gradually venture further.

I was just wondering because it's so clean looking where all your hoses are.

suggestions:

I assume the hinge is already mounted to the door.

If so, through some trial and error use some gorilla tape to tape the part of the hinge facing the dash into place. Trace the left and right side and bottom of the hinge if it is out of line so you know where to move it outside the lines to adjust it and re-tape. Once you have it in place you can then tape it more solidly to the dash and mark the screw holes.

It's basically what I did to line up the holes to drill out for my upper seat belt mounts.
