Ooh type 4 engine, yes there is a spacer and they should be splined head bolts if I remember correctly. Alternator bracket is slightly curved with a 90deg on end where it bolts to block. Looks like a wanted ad then.
Glad you was paying attention then Dav, as that don’t look nuffink like the type 4 that I got hidden under a bench in my garage.
if you need type 4 parts and nobody comes good on here, the LateBay is always a good shout for a wanted ad.

There are two brackets for an alternator on a VW Type 4 style air-cooled engine.
The pivot bracket attaches to the bottom of the engine's cooling-fan housing
The curved, alternator V-belt-tension adjustment bracket, attaches to the top of the engine's cooling-fan housing and the right-hand exhaust heat exchanger.
I cannot remember for sure whether the mechanical fuel pump has a spacer on a VW Type 4 style air-cooled engine, but I don't remember removing one from either of mine.

I have the 2 types of brackets for the alternator and as above I don't think the pump has a Spacer

That's pretty much as I remember it too! Some of the alternator brackets get horribly rusty with little structural integrity.
With these Type 4 engines, one often finds that certain essential components are commonly missing, which typically include the non-return air-flaps & covers, between the engine cooling-fan housing and the exhaust heat-exchangers, plus the left-hand exhaust heat-exchanger & silencer support bracket.

Fuel pump has spacer, called "Intermediate Flange", VW part # 021-127-303A.

Back in the early-to-mid 1990s, I worked on three or four 1972~79 VW 17/18/2000 Type 2 engines (two of which were my own) with twin Solex carburettors & mechanical fuel pump close to the flywheel, but none of them had this intermediate spacer, so far as I can recall.

I wonder if people shortened the fuel-pump pushrod [said to be of 139•8 mm standard length], to compensate for the lack of this phenolic-resin spacer!?! I did something similar, when I reduced the thickness of the fuel-pump spacer cum guide-tube by 6•0 mm, in order to retain the upright "dynamo-style" fuel pump when retro-fitting an alternator, to my family's 1973 VW 1600 Type 2, AD-Series engine.
