Bob
BTW, where are you and the car located? Maybe some of us in your proximity
would like
to offer a physical hand and some moral support to a new MG owner. MG people
have been
known to do that. They will also give you great advice like replacing the
clutch and
throwout bearing while the engine is in surgery. Be happy knowing that this
didn't have
to happen at home just before winter; it could have occurred while on a trip
200 miles
from home this summer.
Now, don't make me look silly by telling us you live in the Yukon or Argentina.
. .
but, come to think of it, I haven't been to either of those towns yet. Maybe I
will
show up to help.
