Request to Panther, JagdPanther, BergePanther owners.
I need to arrive at a one-size-fits-all dimension for working tow accessories to fit the jaws of the "Deckel-Mittelkupplung", the towing point on the rear plate. Specifically I need the internal width of the jaws, or between the bosses if you have added them.
There is some likely variation between the kit jaws and the various super-detailed examples people have created over the last few years. The published drawings also vary, and scaling up adds error. So, please, any actual off-model measurements would be handier than real-world 1:1 reference dimensions.
The pin should be 9.8mm dia to a 10mm dia hole, according to most drawings and publications.
The jaw gap dimension probably will fall between 17-20mm.
I can't measure my own kits.. as they have gone to new homes.

Many thanks to anyone who takes the trouble to measure and respond.
cheers, Fabrice
