What's the dia in mm, mate?!
is it a real stock ek9?
I believe inner diameter is 2,2"
That's probably the correct size as AFAIK its 57.2mm inside diameter but could be wrong
I dont have the backbox to go with this unfortunately,Its in great condition and a decent mod for someone wanting to go for an axle back on an EK4...
60euro,
PM me if you want pics
