I just discovered that the diff flange on an MS112 Crown F-series diff has an identical bolt pattern to a Sprinter S-series and T18 T-series diff. Who would have guessed that?
I pulled a tailshaft off the F series in an earlier crown (maybe MS6?) and it didn't match the MS112 flange. This is when I went through all the other crap in the shed and discovered the T/S flange fitted.
