I want to know the part number for the distributor originally fitted to a 1975 1800 auto bus, also the advance specs

Not sure what came on the auto's but most Aussie dual carb 2.0L and 1.8L manuals came fitted with SVDA's P/N 021 905 205 P
Centrifugal advance at 3400rpm 20.5-24.5deg
Vac advance at 7.9"Hg 8.5-11deg
(taken from the Bently manual)
If some one knows the specific model for the Auto I can give you the specs.

thanx for that andy. have got one of those dizzys but the plastic retainers for the flyweight springs have disintegrated so will have try and remap a beetle dizzy.

Man your keen. You can't find one at the wreckers? They aren't that hard to find.

RedKG,

There has been a recent discussion on ShopTalkForums about distributors that you might find helpful.
