L-series distributors are nearly the same as A-series but uses a spacer/riser to mount to the engine (the pedestal). J-series is like the L-series in using a slotted tang drive, but uses a thin pedestal. It is more like the A-series in that the shaft has no tang, but the tang is in the drive-end.

Overview

Album 14132 Album 14134

Differences from A-series:

• Require a "pedestal" or "base" (Distributor Support) that bolts to the engine, and the distributor is inserted into
• Clocked differently (timing plate tab is at a different position on the otherwise-identical distributor body)
• Has a tang-drive shaft (A-series has a plain shaft with gear fitted)

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

Types

L-series early points: D4n small cap
L-series late points: D4A large cap 
L-series early EI: D4F remote ignitor type
L-series late EFI: D4K matchbox type
Z-series 4-plug: D4K matchbox type
Z-series 8-plug: D4N

Support

The distributor support or base is sometimes called the "pedestal".
