Need measurements spacer/ring WRD

[Eminent]

Hello members.
Is there somebody who can give me the measurements from the metal spacer/ring where the thermostat form the WRD is resting on?
It's from a 280 SEL 2.8 engine form '68.
Thanks!

Hi,

New thermostats are now supplied with this spacer:

Thanks very much Naj. The ring i have here is 12mm inner and so the thermostat doesn't fit. Strange because i took the ring form a 250SL.
Thanks again for your help.
