Hi guys,
Looking for help on my wife's Sept 64 SJ convertible that I am installing a factory air con unit into.
I've seen a few fire walls at the only Mustang wrecking yard in the state (Victoria, Australia) and it seems that the two air con hose holes are one above the other unlike on my Dec 65 NJ car where there is a larger horizontal oval punch out panel. Is this correct for 64's to have these two holes. What's funny is that they were all in the same place but they all looked like they had been cut out with a hole saw and not factory punched. Did Ford use a template on the firewall for the 64 1/2 - 65's to drill these out maybe?
I have a patch panel for the fire wall but was also wondering what the hole sizes were for the hoses to go through the radiator support panel and if anyone can supply photos or measurements or a template for correct locations?
Thanks.

Early '65 cars with A/C had the 2 holes one above the other, unlike the later style. Most holes like this were not punched, contrary to popular belief, but rather a regular hole saw used.

Thanks Charles,
So would the vertical holes be correct for a Sept 65 SJ car? Do we know the cut off date?
Edit: this should read Sept 64 SJ car.
Thanks,
Daniel.

Are you certain it was September 65 not September 64? Interior firewall pads are different between the different periods. Believe there are three San Jose style ones that were used
Do we know the cut off date?
I've got the horizontal punch out starting on cars with projected build dates around the first week of April 65 at San Jose (example 5Rxxx206432)
End of April projected date example - just because it was easier and a better picture

Correct Jeff,
My mistake. It's a Sept 64 SJ build. Thanks. I'll edit the question.
Any info on the radiator support panel holes at all?

Yes, changeover was later, have seen SJ cars in Feb '65 with the stacked holes.

Here is a pic of my firewall AC hoses from the inside. Schedule build date 10/29/64 SJ:

Thanks Chris,
You wouldn't have pics of the holes on the Radiator support panel by any chance?

I have this from a customer coupe scheduled build date 01 July 64 Dearborn. Unfortunately I did not take the upper hole but I can tell you it is in the same location as any 65. What changes is the hole in the firewall. Here there is one large hole for two hoses and wire.
The whole AC install looks factory. i.e. when looking at sealant marks but cannot say for sure 100%. No trace of a holesaw or from a file on the firewall, just a clean cut. Considering the location of this hole on the firewall, it is difficult to make it with engine and pedal support installed, feasible but not easy. This makes me think the firewall hole was drilled before the power train was installed.

I would have to say that is a dealer or owner installed setup.

These are some photos I took from a restoration I did 15 years ago. Holes were factory punched on this midyear '65 Dearborn Coupe.

Thanks a bunch Ray. Any chance of getting the hole sizes?

I measured them at the time for future info but have lost track of all my notes; I actually need them for my current project as well.
I'll see what I can find...it's possible that I've asked this question on this forum...don't know for sure. If not, I'm sure someone out there has the answer for us both. If not however, buying the bushings and measuring them should give us the answer.
Thanks

I think the hole size is the same as the ones used on your seat plugs under the car. Try your AC grommet in one of those holes.
-
Top hole is punched at 1.25" on my 65 Dearborn coupe. Guessing both holes are the same?
-
OK Daniel,
I actually lucked out a bit...still have an original upper Radiator Grommet.
The Hole Size is approximately 1.25" but I would start slightly smaller; taking away material is far easier than putting it back.
The Grommets are available in sets, 378264-S, through NPD, (National Parts Depot), and other suppliers I'm sure, or you may be able to find good used originals or NOS Grommets. There is a difference between the two in terms of the inner hole sizes in each Grommet. The upper Grommet has a 9/16" hole the lower has a 3/8" hole; this applies for the Grommets at the firewall as well and are the same as the Radiator Grommets. The sets from suppliers include one of each size needed.
I don't have any info on the exact locations where the Grommets go through the firewall. If you have an original firewall pad that's intact, there are punch outs in the pad that will help locate where the holes should be punched through the firewall. If not, hopefully someone else has the dimensions.

The original early pads have no punch out - in those examples you'll need some help from another car with AC from that plant and time period

More good fortune...
My Firewall Pad, January, February 1965 and original to my car has the stacked hole cutouts. I'm assuming that the hole locations were the same or very close for each of the factories at that time even though the pad textures varied.
It'll take me a little time to get the most accurate measurements from the pad that I can, and will include a photo or photos of the pad with the dimensions. As I understand it, they are important not only for restoration purposes but also for the A/C Hose lengths, the terminating ends of which may not reach if the holes are too high or low, effectively making the hoses too short.
