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:
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.
