[Healeys] Swapping overdrive drain plugs

[Bob Haskell]

Simon,

The oil pump housing (#61) is press fit in the OD casing. Removing the 
two screws (#63) and washers (#64) to get a socket on the threaded plug 
(#62) shouldn't mess things up.  See tool 18G183 in the workshop manual 
- it's what's used to remove the pump after removing parts #65 - 69.

Cheers,

Bob Haskell
