Instead I pulled everything I needed off that engine to use on my spare engine which acctually was based on a type-3 enginecase.
Original engine partly stripped.
The spare engine partly assembled.
Desided to use a doghouse type fanshroud as the type-3 enginecase didn't have any oilpressure sender mounting hole in the case. With the doghouse shroud I could use the type-3 oilcooler and mount the pressure sender on the cooler instead.
I also made me a tool so I could easily replace the jolting upper hingepin.
