Howdy, been fixing up this clk500 with only 77k miles (just got it fired up after putting in entire new fuel system after it sat for years, yay!) and I'm currently ordering the last batch of parts (I hope). My question is: what diameter center caps do I need for the 17" AMG wheels on an '04?

I had ordered some years ago on eBay that were too big, but looking through my purchase history it only says "MB center caps" but not the diameter they were. I want to say they were 75mm, but it's been 7 years (had ordered them when my mother still drove it, was her car that she bought new) and I don't remember and have no way to verify the diameter they were. 75mm on a caliper almost seems too big, and measuring the inner diameter I got something like 72mm.... most options I see are 75mm but there's also some 70mm. any advice would be greatly appreciated, I'd like to order the right size the first time around if possible. Thanks for reading!




Caliper is set at 75mm but it seems too big, but I'm not sure. ID measures about 72 or 73mm


These are the wheels on the car

To add to the confusion, Autohaus az lists the right size as 70mm. But that almost seems too small. Really wish I could confirm what size the old ones I ordered in 2017 were... no idea where they ended up though, we've moved since then.

Bump? Pls? Nobody had to replace their center caps before?

From my understanding it should be the standard 75 mm. Part Number 6-6-47-0202.

Awesome, thank you! Luckily I already ordered that same part number a few days ago through Ebay. Oddly enough, some sites say the 6 6 47 0202 is 2.95" or 75mm, others say 2 7/8" or 73mm. But I got the part number from a MB parts site, and I found a seller on eBay with new OEM caps that was willing to sell for $8 a piece! Personally I think the 73mm is correct, will measure them when they arrive and report back.

You, sir / madam, were correct. They indeed measure 75mm and are a perfect fit. ....what the heck size did I buy last time? At any rate, thanks again!
