Say Ernest,  read the recent report by Todd on the Ford Evaporator cores.
It appears from his coolant flow tests that the Ford evaporator core
actually flow more coolant than the GM cores he tested.  This is in contrast
to the results of the article in Contact! I mentioned earlier.  Therefore,
my cautioning folks about not using Ford cores based on that article appears
to be in error.  Just wanted you to know.
