While I have not installed one I have done some research on both Vintage Air & Classic Auto Air. Bot will install with minimal changes. Look at their websites & pull the installation instructions for each. AS well there are a couple of installs documented on this site that are worth a look . I believe Vintage Air also supplies parts for factory AC systems as well. Worth an ask. Another option is the reproduction airboxes that are now available. I'm sure additional small parts will need to be sourced.: https://www.google.com/search?q=1969+mustang+ac+box&rlz=1C1GCEA_enUS833US833&oq=1969+mustang+ac+box&aqs=chrome..69i57.3375j0j7&sourceid=chrome&ie=UTF-8

Throwing a pickle down the hallway...

I agree one needs to be careful with what is purchased at the local auto parts store. As long as you pay attention to the parts being ordered, filtering out the lesser known, there should be little problems. I this case I believe the switches NPD sells are those from Standard Motor Products, same as O'Reillys lists. Mike

Picture looks the same. Might call and have them validate it is the same as the picture: https://www.jegs.com/i/JBA/578/6656P/10002/-1?gclid=CjwKCAiAxKv_BRBdEiwAyd40N_-QADGBWiBwu0KQ11xQe47ZJevM_1R59IwShm9Tafhetyz4eCtYKRoC-OIQAvD_BwE https://www.autoanything.com/exhausts-mufflers/77A2280A3697634.aspx?kc=GOOGADW&DZID=PLA_g_1776970260_69104271516_2280-3697634_t&utm_source=g&utm_medium=cpc&utm_campaign=1776970260&utm_content=69104271516&utm_product=2280-3697634&gclid=CjwKCAiAxKv_BRBdEiwAyd40N6huwrefNsz3zFE09QR0YvCpOt-RvksteECeCKfoYPUzpdUjEzAf5BoCdKwQAvD_BwE https://www.hoonigan.com/products/jba-headers-jba-cat4ward-headers-power-steering-pump-drop-bracket-ford-mustang-390ci-v8-automatic-transmission-1967-1969?variant=3221059

Concours forum is great for this type of info: http://www.concoursmustang.com/forum/index.php?topic=9607.msg56720#msg56720

Thank you for the offer. My comment about the dash was really a curiosity. I'm looking for several small items. Unfortuly the car was pulled before I received a response. I hope someone acquired it that may put it to good use rather than a crusher.

I was looking at the same car but have not had time to get down there to take a look. I assume the dash, console & rocker moldings are already gone.

May wish to look into this bracket: https://www.npdlink.com/product/bracket-throttle-cable/210693/203258?year=1969

While I do not know for sure I would say it is functionally the same but different manufacture source and finish treatment. Note the concours is the same shape and listed for all 4v applications except the 390. In my opinion all 4 would work for your application.

The shaker has some adjustment with the 3 screws that mount the scoop to the midplate.

When the lower control arm to chassis bolt was tightened was the car setting with full car weight, engine and trans included, or was it on a jack or jack stands?

If it goes south again I would recommend a Motorcraft SW7663

Item #3 newly listed here, no it is not mine: https://www.428cobrajet.org/forum/index.php?topic=27793.msg187361#new
