James,
The Jr Venture ones worked for me , its not really a recommendation , but they did work well. They were from the very first venturecp that came out. so i don;t know if they have changed at all. i doubt they would have. ask though. id hate to steer you wrong.
k&S is the brand name. Here they are at Ricks,

you can buy them other places as well of course , try If you are in Singapore try Rotor.com they stock K&S parts too i think..

KC - Good point about the woods , im not really sure what it was most likel;y a combination of all the above things. I do remember after replacing the swash, dampers and getting rid of the bushings, that the tracking problem was a whole lot better though.
