I did confirm today that the GM 3941105 DD Deep Grove Power Steering pulley is an Authentic GM assembly one showing clear machine press roller hash marks on the back side edge that a reproduction does not have, also no reproductions were ever stamped lightly like this one is.

These new photos show a few close ups of the machine press roller hash marks near the back side edge and how lightly the part number was stamped on the front as it was bead blasted today. I would recomend having the pulley powder coated for best results in showing off the part number.

Also a price reductions on all the deep grove pulleys as follows, AB Crank now $300, DD Power Steering now $400, AP Water Pump now $100. Shipping add $10
