Tow release pulley needed for DG 100/200. Anyone have oldstock parts?

Thanks for reading.
The pulley located below and aft of the seat in my DG 100 is worn and I would like to replace it.
It looks like the same is used in the DG 200

The manual has the part described (hand written) which states:

M6 x 24 ln 3037
4 x 6.4 din 125
M6 din 985
1 zeieng (?) B37

That may not actually be what it says, but I can hardly read it.

Anyway, was hoping someone may have the pulley or figured out how to replace it whilst avoiding the DG tax.

thanks!

I have a barn full of broken birds, give pulley size, material, cable size, etc and I'll look around. I am willing to do my part to prevent DG from getting their $400.00 blood money!
