Scharfenberg automatic coupler dimensions

[Re57k]

Not sure where to put it, so I'm just going to put it here.

I am currently modelling an e300, and now all that's left is the coupler. Problem is, I'm unable to find any dimensions related to a scharfenberg coupler. Drawings yes, but no dimensions/technical diagrams. If someone does have any information related to it, then please post it here (preferably in metric).

Thanks in advance.
