We're talking about pickup mounting rings, right? Stew-mac doesn't seem to sell the flat ones in plastic, but they have them in metal. Either way, I recommend a different supplier, since their metal rings cost a fortune. I like Guitar Parts Depot (http://www.guitarpartsdepot.com) and GFS (http://store.guitarfetish.com/), but I don't know if they ship to Australia, or if it would be worthwhile even if they did. Maybe try your local guitar shop or Allparts dealer.
Ye where talking about rings here.
Do you think it would matter if I just bought two of the 7/16" plastic ones & used them?
The slite angle dusnt really effect the pickup does it
