Yeah, I have noticed that they are relatively rare in australia given their import status. In an effort to get a new rotor, i contacted several different places around australia, and found one place in adelaide which had one, but they would only sell it to me with the rest of the distributor and cables, so I purchased it. Upon receieving it though, I was saddened to find that the rotor was damaged in this one as well due to the fastening bolt rusting and expanding, thus cracking the rotor around the base. Thats the reason I wanted to find a product to dissolve the rust
I've been advised on another forum to try using RP7 on it and tapping it with a screwdriver, but putting a flammable chemical in an enclosed chamber with sparks makes me slightly unsure about that option.
Thanks for the part numbers - I'll give Toyota a call and inquire about a replacement and see where I can go from there. I've called them in the past, but not knowing the part numbers made things rather difficult.
Eventually I'm still going to see about replacing the ignition system anyway as i've been advised an electronic system would make things more efficient and easy to tune, which would be great, but if i can get my hands on a replacement i'll use it until I have a a better Idea of what to replace the current system with.
Thanks for your help Hiro
It's much appreciated
