Hitachi D4R series Electronic Ignition distributors are used by many/most 1980s era Datsuns, such as the E15 Pulsar. This can be modified for use in a Datsun 1200. It has a much-improved advance bearing plate, which was the bane of the 1974-1982 D4A points distributor, as well D4F and D4K EI distributors. This new D4R type uses a screw-on cap and improved rotor.

This looks like D4R electronic distributor. It was found in Australia:

This has the one-piece ignitor & pickup (Nissan 22020-15M00/22020-15M20)

Advance Bearing Plate

It has a simplified design compared to the earlier D4 distributors. The plastic bearing race contains 4 ball-bearings (up from 3) and slightly beefier design.

The bottom race is similar to the older Hitachi, but slightly smaller.
