Correct center caps for my tarantula alloys?

I'm looking to buy the correct set of centre caps for my tarantula alloys on my GTI. I bought a set off someone thinking they were correct ones but they were not. Here are the ones that I bought… Which style of wheel are they actually off?







Does anyone have the correct part number for the ones that fit? Better still where to buy them from?

Hope someone can help  

I'll have a look in the morning.

Here are mine.





Same number. No one has said that mine are wrong in 13 years! 
Que someone saying just that!!! 

Well that's strange. Yours has got a number 3 at the bottom and mine has a 2. Could you measure the circumference of yours please dano? 

Been away this week, I'm off at weekend so I'll do it then when I'm washing off The Lake District crud from Hardknot Pass! 

On one of the others, mine has a '2' also!!! 
And the code 321 601 171 C 

They'll be a standard fit for standard wheels.
