Thanks for this William. I will continue my search for an alternator and distributor dated accordingly. Any confirmation of dates commonly found on smog pumps for an 02D build?

We have little data on AIR pumps; many were quickly removed.

The pump was installed on the engine dress line during final assembly. At the time your car was built [March 4] pumps were dated about 40 days prior. So, a pump dated 023 91S [January 23] or thereabouts would be acceptable.
