Hi Barry,
Not looked at the video, but from the dash panel view it looks similar to the F12 Dennis I restored for Manston Fire museum many years ago. I have a parts list for a B60 military engine with wet sump, it has no illustration but the RR part number looks like RE11696 Washer, packing, oil pump pedestal, 2 off per engine. Give my friend, Richard Banister a call on 01797 253211, he is the RR parts guru and could well have what you need. I am pretty sure this is what you are after.
regards, Richard
