Has anyone had occasion to replace the core/frost plugs on the pre war Nine engine? If so, were you able to find some with the correct fit or did you have to modify.

Found some on ebay readily a couple of years ago. As I didn't have a digital calliper at the time so I bought two sizes and fitted the tightest fit. No problem since.

Further dig shows I bought 30mm and 1 3/16" at<£2 each. Can't find the leftover!

Thanks Neil. Sounds like 30mm is the size. Did they tap out easily or did you have to break them open?

It was rusty so punched a screwdriver through and levered out!
