We are getting all in accord to install engine in 67 GT350 1341 and I now noticed the 2 holes circled in red. Can anyone identify if these are factory or Shelby added or if I need to remove them.
Thanks

Slightly off topic, but I notice the unevenly spaced holes on the firewall for the export brace. Have you?

No telling why there are holes there. Not factory and not typical of any 1967 Shelby.

You need to remove the holes if you want the firewall to look factory original.

The cowl brace hole pattern in the picture is typical of 67 Mustang.

The hole pattern is the same regardless of it 67 Mustang or GT350.

Thanks for the clarification.

Oddly enough my Shelby, built in the same week, has a similar punched in hole.
I'll have to run a screw through it, but thought it was for the ground strap, albeit incorrectly located.
Are there any late February or early March '67 SJ cars with similar holes?
(I need to check the parts car as soon as I get over this cold).
-
Mine is further over than Carl's pic.
What is weird is that the holes are not drilled but punched leaving a crater.
I'll dig into my disassembly pics and see if there is anything there.
So far it's just an odd coincidence and that our cars are not that far apart on Ford build date.
Update pic to add red circle.

Bill I am thinking like you on this. If someone wanted an extra hole in the firewall they would just drill it. I do not think it is easy to create a hole like we have on our firewalls by punching method in these radiused areas to result in a hole within a depressed crater.
-
I'm reluctant to drill a hole in the firewall as I don't know what's on the other side. An awl or punch "seems" safer.

I thought Ford liked to do punched holes since the metal deforms and splays giving a lot more surface for a metal screw to bite.
This looks rather severe.

I found some pics of when the car was up for sale. Yes, I keep almost 40 year old pics. The hole was there with nothing in it.
This car once had aftermarket air due to its location in the deep south. Lots of holes had to welded up. If I put my smart cap on this may well have been a way to feed a 12V electric line directly in-line with the inside evaporator. It could also be a way to to send power to the A/C clutch.
Time to make that hole go away.

Elementary, my dear Watson.

I too found some old pics from when we acquired the car in late 80s and nothing in the holes...it will remain a mystery
but now is the time for the disappearing act

If it was a hole for a wire then that's right up your alley!

Bossbill, 1242 has a punched hole in that location. There is a nylon tie strap in that location (same as shock tower harness straps). The strap holds both the choke cable and the alternator gauge harness close to the firewall prior to their entry through the firewall. This is how I found my car - can't say if it is factory, but sure looks like that was original intention.
Makes sense that although Ford wouldn't use a hand punch to make a hole, Shelby would.

This is what was going through my mind when I noticed these on #1341.

I'm writing to Dave Mathews to see if he has heard of this. It might just be a narrow application.

Agree the holes mentioned in the first post are not original

Its not :) Holes was a product of the build process at San Jose so is shared with K code Mustangs built there
The strap at least is a reproduction and not original to the car. Originally there was a metal half clamp that held the choke cable not the wire or loom. Location of the hole can vary depending on possibly worker or when the car was built at San Jose
Of course found a number of examples where the prior owners repurposed the hole and different retainers to hold the Shelby wires, transmission wire loom or a combination of items
Examples from early through #2650

Thanks Jeff. I should check for evidence of threads in the hole. Looks like the half clamp is similar to brake line clamps seen elsewhere. I was not aware that Ford would use such a crude method to create a hole, but I guess that's just the way it was.

Crude?? Well not normally just depends on the plant and the process/part. There are examples of other plants and years where the choke cable hole appears to have been made with a punch and a big hammer. ::) That is why we look for multiple examples - same plant, production period, options and such to form opinions
