Hello mate and welcome tyo the site. Its great to see any International intrest on here, we already have quite a few members on here from the States and many are members of the Tercel forums as well. If you have a build thread on another site you could post the link in the Members car section or even better copy and paste it into a new thread on there so everyone can see it. Here is a quick link to it mate, you just click on Submit members car and fill in the blank space below. You can come back anytime and edit it to add or chance it.....

Thats were most members will see your request and many will post up even if they dont have the parts you need but know of someone who has.
The advance search at the top right corner of the screen may also help you find what you require, there have been so many things covered on this forum in the 10 years it has been going that some gets lost in the mix, but i dont think there is much that has not been covered.
