So, of course, I can't find any plate that fit on this size of treads... after several research on google who make me crazy the only resulat that I found is a relocation kit for Dodge Cummins with 1" inch thread but in 16 unf

So I came here on this side of the earth try to find the graal of our engine I've you got an idea or something to can help me ?

thank you !

12 UNF translates into 12 threads per inch & 2.1mm thread pitch.
I'm not sure about that though.
Nissan usually follows standard common thread sizes. 2.1mm thread pitch for an oil filter looks bit too high.

This is the one I used for RB30. I believe RB30 & RD28 blocks are quite similar if not the same.
