Paul I found this front end spindle, but not the pulley. I picked up the
water pump pulley instead.

Note the Key at the 9 O'clock position and the screw hole at about 8:30,
just below the key.  Also note the dimple at 2:O'clock.  Each of the 4 holes
has a different spacing, as the pulley only fits one way. The water pump
pulley has two notches on the rim, but will not fit the hole pattern of the
spindle.


I think this is called a pulley hub and not a spindle.

I am not sure I follow you on this Jerry. "I picked up the
 water pump pulley instead." I think this is confusing you. I think
what you found was an e-shaft pulley that did not happen to fit
your e-shaft pulley hub bolt pattern. Of course there is no
fixed angular relationship between water pump pulley and e-shaft
pulley because of the V-belt.
