These are the numbers on the pulleys I have that arent on a truck.

Power steering pulley-3925537DC, came from 1970 GMC suburban 4x4 w/A.C.
Crank pulleys- inner 2 groove- 3744043BA-outer 1 groove-3751232BB, not sure what year but there either 1970 or 1972 but not from same truck as power steering pulley and from a non A.C. truck.

Also have a single groove rear crank pulley with # 3755820BC from a 67-72.

I have 1 more set on a motor outside. If the rain dies down Ill go out and get them off today. They came on my 1971 chevy 4x4 without A.C.

I dont have any of the other A.C. pulleys. Sorry. I only got the power steering one with the truck and it is for sure an A.C. pulley. It doesnt line up with my non A.C. crank pulleys. All the other numbers I gave you are for non A.C. pulleys.
