[Healeys] Core plug query

[Michael Oritt]

Simon--

It's hard to tell as the pic gets blurry when enlarged but it is almost
certainly a screw fastener that connects to a strongback which draws up
tight behind the block's interior and positively prevents the plug from
popping out.  I'd appreciate learning the source of the photo as that is
the sort of plug I was trying to source--it would be great to carry a
couple of those plugs for emergency use.

Best--Michael Oritt
