A dizzy question

[icosahedron]

While trying to source a distributor for a DJ engine (see Wanted: section), I've ascertained that the DJ and the later DG engines use the same distributor part no. 025 905 205N. I am aware that the vacuum advance units fitted to the distibutors are different and also that the DG has a rev-limiting rotor while the DJ has a standard one as revs are limited by the ECU.

Are there any other differences that anybody is aware of? I did consult ETKA but am none the wiser.

no that's it hall sender and physical distributor are the same just the vac advance unit that varies and the rotor if fitted with rev limit one but not necessary
