Monza dust caps

[B7TMW]

Need a set of matching valve caps for my 18" Monza's. Not sure what would have been on it originally but currently it has the attached (but only 2!!) I would like to replicate these with a new set but searching eBay, I can find a few that look the same but mostly it's one extremely annoying seller (Argocity) who lists pages and pages of the same after market tat rather than list one sale with multiple available! It's infuriating.

So, what was on it originally (was it the attached?). and where do you guys get them?

Cheers in advance.

I'm also looking to replace the nasty arse set I have on my monzas and agree that ebay isn't great for originals. I'm thinking about going into the local vw garage and getting a part number from them (if there is such a thing for them) and then try the Internet once I know what they are.

I'll post it once I've been in

I went to VW and they only list the full valve as a part. I'm still looking.

Just so you know, that isn't an original VW valve dust cap.
Also VW does sell the original metal caps separately as I've got them in the past.
