pls explain...............

all i knoe is that i have bigger ones in my sprinter now and i got those out of a zenki jap spec rear end (drum to drum)bought from SSS automotive spares.

the ones i have lying around are smaller as i found out the hard way. so i assume it is a zenki diff. either way i have the axles to match with the diff im selling.

...hmmmmmm so from what you are saying is that the ones i have now are zenki jap spec axle? so what size or difference is the kouki ones?
