What battery are the Tbird owners using. Interstate apparently makes a "pure lead" replacement with vent caps leading to corrosion in and around the battery box and needs the cells routinely checked for water levels. The Tbird Parts outfits want a paltry 300 bucks for a sealed look-a-like, as does Batteries Plus. I am getting ready to fudge a Motorcraft into the Bird but it is going to look a little awkward.
