Thank you all for your suggestions as far as my two leaking heater cores (1961 300G and 1962 NYker wagon, both with factory A/C) . Club member Bill Buechler contacted me, offered his shop's services, and was able to recore both units in his New Jersey shop. Bill made it easy, quick and painless with a fast turnaround! You may reach him at billsolds@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx if your core springs a leak; he says he has enough material right now to do a couple more, and will look into getting more if need be. This 300 Club rocks ! Warm and dry in Sag Harbor NY John Hertog [Non-text portions of this message have been removed]
