If the plastic base plate isnt phenolic and nit too thick I could CAD draw it and cut it out at work on the laser cutter. Same with the gasket. Let me know.

The 356 gasket is fiber, so am unsure if the 911 version is phenolic or not. Regardless of material, I think there are plenty of modern alternatives, perhaps Delrin or UHMWPE, etc. All of these are easy to laser or waterjet cut. My thought was along the lines of what you suggested: making a cad drawing and using it as a path for a CNC cutter. I am skilled at using Solidworks, so was going to make a model. My challenge was access to cutting machinery, but it sounds like you have it covered!
The only wildcard is thickness - finding out the actual thickness is critical, as it sets the base range for adjustability of the actuation rod. With this thickness, I could source an appropriate material and hopefully not have to fly cut the material to get the thickness to spec.
Does anyone have a base gasket that they could throw into a micrometer?
After a quick search, Auto Atlanta shows that there are two components: an insulator, which is still available, and a paper gasket, which is not. I am going to order the insulator and then use it as a pattern for a paper gasket. Link:

They also show the part number for the crimp fittings, but say they are NLA:
cap -SOLEX: 901 108 584 01
Stoddard doesn't seem to have them, at leat on their website.

About the Fuel Pump Base
Fuel pump bodies for both the early VW and Porsche engines consist of lead-zinc metal castings which are relatively soft yet brittle. With age, they can oxidize and when subjected to continual pressure as from the pushrod, they can warp. On virtually every fuel pump we have seen. the pump base is warped which in turn creates the nearly ubiquitous oil leakage around the fuel pump commonly associated with the 25 hp and 36 hp VW engines but also found on later engines. While we resurface the fuel pump base to create a better fit between it and the resistex base, you must be aware that warping of the base will resume as soon as the pump is put into service again although this progresses relatively slowly. The base can of course be refaced periodically to minimize the affects of the warping in terms of oil leakage. However, eventually enough metal will be removed that the base will no longer be serviceable.
Auto Atlanta shows A LOT of oddball solex carb parts in stock, inlcuding the ball pin and bell crank. I am going to roder them and see if they come through:

Hi Kenik
Thanks for the picture. Can you measure it? You think you can find one more? ;-)
As for the gasket, it seems that our Paul Abbot has one currently. May be he can measure?

Hi Richard,
I have a base gasket that came with my mechanical fuel pump. I'll see if I can remember to measure it at work tomorrow.

Hi Kenik,
I took four measurement, 3.55 mm, 3.54 mm, 3.59 mm, and 3.57 mm, which gives me an average thickness of 3.56 mm.
Do you know what the two ports that I have labeled 1 and 2 are for?
Thanks!

No. 1 is definitely for the center lube cam oiling line. No.2, I am unsure but will look at my car. If it isn't there I'd say it is for a 68 air injection system.
