Here find Glacier and Vandervell catalog pages for crankshaft bearings for Austin B-series engines .
Crankshaft Bearings for MGs, Glacier -(pdf)
Crankshaft Bearings for MGs, Vandervell -(pdf)

Note that both Glacier and Vandervell have no numbers for Twin Cam main or rod bearings.
Also their numbers for MGA 1622 engine main bearings are wrong, giving same number as for 1500/1600 engines, ignoring narrower center main bearing in the1622 engine.

Vandervell thrust washers cross to BMC numbers that are real and do exist.
Vandervell other referenced BMC numbers do not appear in any MGA Service Parts Lists.
