Lower Radiator Hose for 1969

Short answer: For a 1969 350/TH350, the lower radiator hose should be about 1.75″ ID on both ends (and fairly short, ~15–18″). The Ames hose with a 1.5″-to-1.75″ flare was the wrong part — too long and the wrong diameter. A correctly sized lower hose is commonly available at NAPA.
