Default Better than original? Dressing up an aftermarket A/C unit

A little project I've been playing with for the last few months:

The previous owner of my 66 convertible installed a Classic Auto Air "Daily Driver" underdash A/C system. Being in Florida, this is certainly a welcome modification from a comfort standpoint, but it leaves a lot to be desired from a visual standpoint in my Ivy Gold / White Luxury interior.



The good points about this A/C unit are several:
It cools pretty darn well
It uses a modern Sanden type compressor and R134A
It's narrower and overall less bulky than an original Ford under dash A/C.

The bad points are:
The black plastic bezel just looks wrong in the car

So, I pondered what to do and went and bought a scrapped original unit to see if an original bezel could be made to fit this new unit... Simple answer is "No, not even close". But I did salvage the original Ford ***** and Ford Crest from the old unit and then resold the remaining parts.

Next I played with the idea of plating or painting the plastic part with chrome finish, but the part is grained and would have required a lot of prep work, and painting ABS plastic is not easy and it would have probably flaked and looked like crap and pissed me off.

Then I talked it over with a couple of my buddies and explained how much pain I was in staring at that ugly black thing, and they offered to help me out. The great part is that my three buddies are a Solidworks specialist, a machinist and a very talented fabricator.

After a few minutes of heated discussion, they said %*$& it, we'll hog it out of billet... and that's exactly what they did. First, the Solidworks guy measured and made a model of the plastic part, adjusting it for the material and machining.

Then the machinist transferred the Solidworks model to MasterCam and went to work (starting with a solid billet), milling this bad boy in one piece.

Test fit. It fit perfectly the first time... then it was off to the plating shop for a really nice triple-chrome plating job.



We then trimmed a glove box woodgrain decal and used the factory ***** and Ford Crest to finish it off.



Close up:



I think I owe those guys a lot of beers.

If you look at a 66 with a Luxury Interior, Console and A/C, the console has black camera grain finish to match the A/C unit (which only came in black), and the instrument bezel and glovebox door have the wood finish. This is due to the fact that the A/C unit has a concave front surface that would be impossible to apply a flat decal onto. Another detail is that the larger Ford A/C unit requires that the console be cut down and capped before it curves up. With the smaller aftermarket A/C unit, the console has a little upward sweep which I think looks nice. Overall, I think the end result is cleaner than factory, but I'm biased.

To answer a likely question ahead of time, the cost of duplicating this part would be very high... there is a ton of machining time involved and these guys don't work cheap... this was definitely a major favor, for which I'm very thankful.

Definitely looks much better, and I too like it better than an original FoMoCo unit. Very great job by you and your buddies!

That looks much better. I wonder why they dont offer something like that.

I had considered one of their kits, but decided to make a hybrid of a refurbished underdash unit but upgraded everything under the hood. I really like to original AC bezel.

There is kits to upgrade the compressor so you could keep the rest stock.

Looks amazing, you should start with buying those guys a keg. You should think about painting the case to match your console, also.
