Back in 1974, VW distributors were designed to work best when paired with a specific carburetor. There should be a number stamped on the base flange of the carb (left side as you're looking at it). If this motor still has it's original carb (not always the case after all these years), that number would be either 427-1 or 428-1.
If the car was originally sold in CA, that number could be 429-1 or 430-1.
For a 427-1 (the most common carb), the original distributor would've been VW P/N 043905205. A 428-1 or a 430-1 (not very common) would pair with a 043905205A. A 429-1 carb used an 043905205C distributor.
Be aware that distributors and carburetors on air-cooled VW motors are easily swapped around and many no longer have the same components that were originally supplied with the car. Plus, there are now a ton of aftermarket carbs out there with no numbers on the base flange at all. If that's the case here, you just have to do the best you can to find a suitable match...different combos can be made to work. If you can get the model number of the carb (on the left side of the float bowl as you're looking at it), that would be helpful in picking a suitable distributor.
