Does anyone know the part number for the "adaptor" bearings. Std T1 main tunnel, std T4 centre main.

I think they are a BMW bearing ?

Yes BMW, 6 cylinder .

Craig at Crankshaft Engineering will have a set in his cupboard with the KS part number on the box.

61 7 38067488

If Crankshaft hasnt got them anymore I know Vintage has a few sets if you carnt find the part number

there much better to use the steel back BMWs than the crap alloy ones the yanks supply wit the case
