L20B matchbox Datsun factory Electronic Ignition came in these USA vehicles:

  • 1979 200SX (S10)
  • 1979 Datsun 510 (A10)
  • 1979 Datsun 620
  • 1980 Datsun 720


If buying used, there are two things to watch out for:

  • Advance plate bearing gone bad ($75)
  • Vacuum advance canister not holding vacuum ($30-$100)

CAUTION: These often go bad after 20 years. Inspect carefully before buying.

If buying new, you will need these used:

  • Timing plate
  • Distributor Support (pedestal base)

The support Pedestals is different than L20B points type, though looks similar the spacing is different: pedestals_c.jpg pedestals_a.jpg

Because the L-series uses an offset-slotted drive, it can be fitted in only one position. This makes getting the correct distributor, pedestal and timing plate very important. It is possible to remove and "re-index" the driveshaft inside the engine, but not recommened. It is possible to use a Z20 matchbox, but all the same problems apply. See Mismatches.
