Damper Plate for new motor

Hi All,
I've just bought a Nissan TD23 marinised diesel to replace by old SD25. My ZF hydraulic gearbox fits the TD23's bell-housing perfectly, but there's no damper plate for the gearbox spline to fit into. I have the old damper plate that I may be able to do something with but I noticed that the TD23 may have an adapter fitted (see pic). My question is, what type of damper can I fit to the new motor so the gearbox can work?


Thanks, Steve

Thanks Woko,
I think that Diecon was bought out, but I will check and look for their products.
Cheers
