Ebay ball links wrong lenght

[Goran]

I bought a pair of delrin? ball links for the intake manifold bellows a couple of years ago on ebay (advertised as for S8).
Finally one of my original plastic ball links broke, so I had the replacement ready.
However I found it is 5mm longer than the stock ball link. I wonder if this hurts performance? Perhaps the flap wont be fully closed/open due to this?
Anyway just thought I would mention it to be careful with buying the ebay ball links they may be just slightly the wrong length.

Now I am going to do as originally planned and make them myself out of aluminium ball links.
