Ford Transit Mk2 1984 viscous coupling unit replace

The viscous coupling unit of my 1984 Ford Transit Mk2 broke and is very difficult to find. So I designed a non-viscous alternative to replace it. The choice of material was to use nylon that withstands the temperature of 180 ° C.
It was a little bit difficult to print it with my Anet A8 but in the end I succeeded and ... It works!

Unit redesigned and made lighter.
