Np203 ???

[Jason4x4]

I got a np203 that has a steel output housing to replace my broken alum output housing. I want to replace the output seal, but all the parts stores are showing is the seal for the alum housing, the steel housing uses a bigger seal. anyone heard of this? or know what year the 203 might be from?
