90009 7.5″ Damper for Big Block FE Ford 352/390/406/410/427/428

product is exactly as advertised. high quality. would purchase againthe manual says to use the provided spacer if you want to keep the stock belt configuration, but I didn’t need it. the attached pulley lined up perfectly with the alternator and fan pulley.however, now the stock pulley that mounts to the front of this product (using the three bolt holes shown in the picture) sits 3/8″ farther forward than it used to. I have to use spacers to push the power steering pump farther forward so the belt lines up.
