Any body out there with a numbers book that can ID the original application for these early BB Power Steering Pulleys?
3925537-DC
and
3925525.
Many thanks...

If those are part numbers (or if the part number is stamped into the pulley), 3925525 shows up as a crank pulley:

0.659 BALANCER-PULLEY-KEY, Crankshaft
68 All w/P/S (396)(exc. Sp. H/Per.) PULLEY, front (1 groove)

The other, 3925537-DC, shows up as that part number as a P/S pulley (without the -DC):

6.655 PULLEY-GUARD-NUT-WASHER, Steering Gear Hydraulic Pump
68 Pass, Chevelle, Camaro (396)(exc. Spec. H/Per.)

Again, the first shows up as the part number for a P/S pulley and the second shows up as a part number for a crankshaft pulley(?). I don't make 'em up, I just read the book.

Dale, Thanks for the info... both pulleys correct for a 68 low horse 396 is just what I was hoping to hear!
Just so there is no confusion, let me clarify my original post... The 3925525 stamped pulley is indeed a crank pulley, single groove add-on. I knew it was the add-on pulley for driving the power steering pump alone. I should have differentiated one as a crank pulley and the other as a pump pulley rather than calling them both P/S pulleys. I'd hate for you to think your book was not correct.
By the way, what book provided this info? And is it available to the general public?
Again, thanks for your help.
