I'm very confused. What's a man. steering pully? Manual steering needs no pully.I thought I could just leave the one groove empty but the man. steering pulley may have a different angle to it.
To answer the rest of the question, though, the '69 pulleys for a 351w look just like the ones for a 289/302. The crank pully will be a 3 bolt. The crank pully went to 4 bolts in '70 and because of the water pump inlet moving to the driver's side, pretty much all of the brackets and pullies changed. All the brackets are different shapes and the pullies changed depth because of the dampner change.
