In an interesting turn of events, I found out I have to replace my heater core today in my 71 convertible. I had given you insights in posts #5 and #16. I recently had my car stored up, on my 4 post lift. I removed the 71 hardtop I had under the lift and lowered the convertible down to the floor. I looked in and I see a few papers I had on the mat on the passenger's front floorboard are wet. I look at the heater box and yes, antifreeze has been dripping. Fortunately, most was on the vinyl floor mat and absorbed by the papers. I had a spare rebuild kit for the heater box. I had to remove the cassette player and bucket seat. I will now get to do my 4th heater box rebuild. Fun. Having the lift is nice to drain the radiator and unbolt the seats. Oh well. I'm glad I caught it before it became more serious.
