Just found a crack along the top of my otherwise perfect original. Looking for one in as good a shape, or NOS like... I followed @techg8 's thread http://www.v8buick.com/index.php?threads/wanted-1973-1975-455-fan-shroud-1243007.359054/ before I figured I needed one as well! Looks like the 1973 one is different than the 1974 and 1975, and the 455 is different than the 350. This is the part number... 1242615 Otherwise, I wonder if a bead of something off white would hold... and be fairly invisible. It's dead center across the top. TIA Dave
