Jack's Comments:

This is a very good copy of standard sized small single pulley for most single sheaved equipped alternators. It doesn't have any engineering numbers stamped on it like most of the originals did and some radiuses are not exact but its the best available by far.

Concours Note: This pulley with a yellow zinc finish from used during late production 1966 thru 1973.  Autolite started to phase out the black painted pulleys late in 1966 production. We do not have a exact change over date but we have documented a few cars with original alternators to give you some guidance (see below).
