Both of my 73s used the longer base, I don’t know how the shorter one would work.

Is this what you're talking about? Regarding bases? Which one is E9 again?
The third one looks the same to me, it just has the extra bracket in front attached to the mounting plate.
The one with the extra window is for the E9, the shorter one for the E24/E21.
The third one in the photo below is installed in a Nevada 2800 imported from the USA.
The front is completely different.

I see what you mean. Could the first one be e3 as the console is very different?
It is exact match to that in my '75 Euro CS.
It appears that the E9 model had two different evaporator bases.
Perhaps these differences exist in the construction of the evaporator base in pre- and post-facelift models.
In any case, the original A/C evaporator base is difficult to replicate.
Every craftsman I spoke with about this said it was certainly possible, but it wouldn't be cheap due to the shape, which requires more precision and time to replicate.
I think the best solution would be to redesign the base to standardize and simplify its construction while maintaining its functionality.
I think the longer ones with a window are only for E9.
I'll keep you updated on progress.
Why not route the air up to and out of the speaker grille? I personally like fresh air blowing at me when driving

Hello after a long absence.
We're slowly approaching the end.
In about a month, a complete air conditioning system will be available, modeled after the factory one but equipped with modern components.
We're currently conducting final tests and minor modifications.
The kit will allow for air conditioning installation in any E9 that wasn't factory-equipped.
Plug and play installation.
No modifications to the vehicle's structure are required.
The system is adapted to the new refrigerant.
The kit will include:
- Sanden compressor with bracket for the M30 block.
- Compressor drive belt.
- Condenser with fan.
- Drier.
- Refrigerant service connections.
- A complete set of system hose connections.
- Refrigerator hose to be cut to the correct length.
- Evaporator with a modern core and fan.
The exterior of the evaporator housing will be identical to the original.
- Evaporator air duct.
- Evaporator base.
- Side panels with inlet openings and inlet covers with an elephant skin texture, just like the original.
- Central panel with markings in English or German, along with modern climate control parameters.
- Radiator fan thermoswitch
- Relay.
The photos below obviously do not show all the components.
We are currently in the final stages of improving the efficiency of the cold air vents, and everything indicates that the next upgrade will be a modification to the cold airflow, which will allow cold air to exit through the windshield defrosters. This will prevent cold air from escaping exclusively through the heater outlet vents.
This should improve cold air circulation in the cabin and cool it more quickly.
All printed elements are currently available. The entire set will be available from mid-March. If interested, please send me a DM.
Questions and comments are welcome.
It's winter, and a friend's workshop is preparing for the season.
I couldn't resist passing by.

The field of technical materials is currently seeing rapid development—specifically materials that are ultra-hard and resistant to both impact and high temperatures.
I recommend the following YouTube channel:

These materials aren't cheap and require a lot of tweaking of print settings, but the final result is excellent.
The prints are strong enough to accommodate threaded metal inserts at the connection points, allowing everything to be assembled just like the original.

Evaporator base featuring a T-bar for securing the evaporator housing and a drainage funnel for the evaporator bottom.
The base has undergone durability testing and successfully replaces the original metal base.
The color of the rubber drainage funnel is for testing purposes.

@ lucas, can we also buy parts seperatly? I have a 80% complete system on the shelf.
(And an 80% complete chassis)
(And an 80% complete chassis)
Good morning, Erik.
Yes, it is possible to purchase individual parts of the system.
Essentially, all the components are ready.
Final tests are currently underway on the evaporator itself; to ensure proper operation.
Upper section required a complete redesign.

Will the new evaporator include the additional air circulation ducts? I also would like to purchase that part with updated fan and new evaporator. My car is with Don and we are holding off rebuilding the original evaporator.
