A lot of parts have been chopped & changed over the years, the DK4A was widely used and had numerous variants for different applications. Also I've known more than one person advocate simply locking the weights up and setting with some advance.
As for loose bits, the best advice I can give you is look out for a less worn unit. The ones with welded posts seem to fare better. Otherwise the 'Distributor Doctor' appears to have cornered the market here. He can at least supply most of what you would need.
