[Healeys] freeze, welch, core plug query.

[Simon Lachlan]

We tend to call them core plugs in UK, but they're the same things whatever
they're called!
We are talking about a 3000, MkII BT7..........
So, how many plugs are there on the back of the engine? (Transmission end)
Are they accessible with the (centre shift) tunnel removed?
Easily accessible or, typically, visible but tauntingly just out of
practicable range?
Thanks,
Simon.
