Where to get a distributor for cheap?

Hope you are in Australia, go to a good breaker yard.
If you are not I don’t know.

Junkyards are teh only place to go for cheap parts. Nut as @Tropical_Willie says, you have to be sure that you are someplace where there may actually be one in the yard. Where I live in the Seattle area, I am extremely unlikely to find Holden parts anywhere; we don’t have Holdens in this country.

@Tropical_Willie cool will check it out. @jerv Seattle I like to visit someday that’d be cool
