Swapping a later model 911 dashboard into a 69? AC vent question.

[Awaadster3]

Hi Everyone, starting to put together the interior of my restomod 1969 911. I have opened up AC vent holes in the dash to accommodate later (1985+) model 911 AC vents. I plan into retrofit an electric AC in this car.

Would a later 911 dashboard/pad (1970s - 1980s) swap into a 1969 model 911? If not, is the center vent opening the same dimensions between the different generations?

Were there major differences between dashboards besides the defrost vents near the windshield? Any help would be appreciated!

Pictures attached for reference!

You will have to realign, and I “think” shorten the defroster outlets. When welding close to the windshield seating edge, be careful not to get it too hot as it may buckle/disform creating new issues when sitting the glass.
BTW, it may be worthwhile getting later G-model outlets from the junkyard.
Good luck.

Thank you for the info! A few follow up questions.

1. I am guessing the picture of the defrost vent openings you attached is of a later model (86+) 911 correct?

2. Would I need to open additional holes or just modify/shorten the two existing vent holes on my dashboard?

3. Once the vent modification is done, does the 86+ dash pad bolt into the existing mounts/clips?

I just did this for my '75. The mounting points under the dash are different. The two studs from the earlier dashes that insert into the metal frame directly above the gauges are not present on the newer dash. Also there are no plastic clips that hold the front-most part of the dash to the frame.

There are two metal tabs that stick out the front that need to be trimmed. Since the defrost vent is the only thing holding down the front of the dash, I kept those tabs (shortened them) and secured it to the metal body with sheet metal screws.
The holes where the front studs enter into the face of the dash sheet metal also need to be drilled out as they are located in slightly different locations.
For the vent holes, I've read of others who have kept the original vents and slapped the updated trim on top and it works not too bad. My vents stood up too proud and required some coaxing for the defrost trim to sit properly on the dash.

All in all, much easier install than the two side vent metal work.

This was extremely helpful! Thank you
