HOLD ON A MINUTE!

It is not well known that the front pulley and hub are a MATCHED ASSEMBLY.
The timing marks on the stamped steel pulley are not consistently timed to
the hole pattern. You cannot safely mix and match pulleys and hubs. Some of
the pulleys are marked pretty close to the same, many are not. You need to
get the position of the timing marks relative to the keyway in the hub, not
the four bolt pattern.

Been there, done that!

Is the relation between the keyway and the timing marks consistent for the same
year (88) engines.
In other words if I buy a set (pulley and hub) I should get the proper timing
marks for my engine.
Where is the TDC mark in relation to the keyway?
Thanks
