Pedestals

L-series distributors are nearly the same as A-series.

J-series is like hte 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

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)
• Have a keyed-end shaft (A-series has a geared-end shaft)

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
