Parts are not very hard to get. They may be for another Toyota, as Noah and Voxy was only made for Asian market. If anyone wants to post places where body and mechanical parts are available, it might help some of us from having to hunt down parts.
So far for the 2005 Noah (AZR60) I got the following parts from the following sources:
Front and Back shock absorbers (KYB) - Chase Village Auto Supplies (F - $650, R - $285)
Boot and buffer for front shock - Chase Village Auto Supplies ($80)
Outer Steering ends - Chase Village Auto Supplies ($240)
Inner Steering ends - Chaguanas Auto Supplies ($290)
Steering rack boot rubbers - Chaguanas Auto Supplies ($80)
