While the engine was out, I shopped around for a pair of used, but good, heater boxes. The 2 pairs I saw were in worse shape than my own and both merchants wanted $75 per box! That's the rustbelt for ya. So I decided to fix mine. Cleaned them up in hot, soapy, water and let them dry for a couple of days. Then painted them with POR-15 (paint over rust), which gives the metal an almost ceramic-like, hard, finish. Finally, I band-aided perforations with aluminum-foil tape, and voila. I'm sure there are more professional approaches, like welding. But I'm just a regular guy (who can't weld), with limited financial and handcrafting resources. So this is it. Btw, the Al-foil can also be used to seal the gaps between the heater boxes and the tubes and flaps, etc., that make up the whole heating system. I noticed a considerable improvement in heating output while driving around in close to freezing weather. -- Sami ('75 Westf.) dakhlia@wuecona.wustl.edu http://wuecon.wustl.edu/~samid/
