Remanufactured and/or new distributors can be obtained at AutoZone and probably other parts suppliers. We understand the AutoZone replacements use newer technology than the original GM distributors and work well. The Fiero Store also has replacment distributors.

Distributor Parts: The distributor gear for the V-6 is rumored to be discontinued but should be obtainable under GM part number 01985769. A worn gear can be the cause for jumpy timing. GM part numbers for other components of the Fiero distributors are as follow:

Part Description          L-4 Distributor   V-6 Distributor
Distributor Shaft          discontinued        10497450
Shaft Bushings               10477565        discontinued
O-Ring                       10477565          10477565
Pickup Coil                   1987964          10495089
Ignition Module              10882835          10482827

The '87-88 four-cylinder Fiero did not have a distributor and used a Distributorless Ignition System or "DIS". Some of the GM part numbers in this system are:

Part Description          Part Number
Crank Sensor                   10496122
Ignition Module                10467208
Coil Pack                      10472401

Our thanks to the May/June 2005 "Fiero Focus" from Northern Illinois Fiero Enthusiasts for the distributor part numbers.
