Thanks Bill - Thats what I will have to do. Found I have 53 heads with the small temp sending tap. Unable to find a smaller sending unit to match the ohms out put needed for the electrical guage. I am getting ready to repaint the dash area and have removed everything. Also rewiring. Considering replacing the vacuum wipes motor. I have the standard heat unit but delux control. Don't need the new cables I got - nothing to control but the blower. Also posted on looking for a driven speedometer gear 20 tooth for my 3 speed. Everytime I fix one thing two more appear. Thanks Tom
