This information may or may not be useful to some folks. The OP has a parts donor. Active vs Obsolete info as of May 31, 2015

The terminals for the 73-91 Delco Analog Radio plugs are not listed as obsolete. They look like they could still be miserable to source as the usual suspects don't stock them.
There are several sources that stock sets of all three Delco radio plugs as assembled repair pigtails.

• Delphi connection systems part #12040500 Active Cu Ti Terminal, Bow Printed Circuit Female, W-Crimp, Cable Range 0.50 - 0.80 mm²
• Delphi connection systems part #12004543 Obsolete 4 Way Black Printed Circuit Bow Unsealed Female Connector Shell {POWER}
• Delphi connection systems part #12004544 Active 4 Way Cream Printed Circuit Bow Unsealed Female Connector Shell {Front Speaker(s)}
• Delphi connection systems part #12004545 Obsolete 4 Way Blue Printed Circuit Bow Unsealed Female Connector Shell {Rear Speaker(s)}

The 87-91 digital radios used Pack-Con Series I connectors or a mix of the above Delco radio connectors and Pack Con I. Pack Con I terminals and connectors are available in-stock from the usual suspects.
