Yeah it is called the stabilizer bar. See this page:
http://www.toyodiy.com/parts/p_J_1994_TOYOTA_HIACE_KZH100G-GRMDT_4804.html
So the bushes that bolt against the axle are 2 times part nr 48815-26140
The bushings at the end of the bar (in the end links) are 4 times part nr 90385-13004
You can enter both numbers on Ebay and find them in normal rubber or poly-utherane
