Wanted to add some more pulley info for clarity, there were several different SB p/s pump pulley pn's used between 67-72. While the 537DC pulley was used on all 68-72 BBC SWP remote fill p/s pumps, we have personally found the same 537DC pulley was also used on SB p/s pumps in 69 & 70, with the more commonly seen 325DJ SB p/s pump pulley being used in 71 & 72 model years.
