It sounds like the advice from Frank or Mark are your best bets. When I had
to do this I replace all of the coolant lines to the oil cooler while I was
at it. However, i think you can get less of a batch if you hose clamp the
rubber parts of those lines (although it's been a while since I looked and
they might not be long enough for that).

Sorry you took a bath - I remember this job and putting that all back
together was a pain because there isn't any room to maneuver. I hope it's an
easier go for you.
