greetings... i am need of an air-con condensor, and a low pressure cycling switch (i want to get these fixed before you can't get r-12 anymore).. i live in canada, so, will have to order from the usa to get these parts (thus, paying $$$$ in duty) i understand that the aircon system in our cars is mostly gm parts.. does anyone know for a fact wether or not this is true (if so, part numbers would be appreciated).. i am asking in this forum, as i have been told that the "cross-reference chart" is not entirely trustworthy.. thanks for your help, in advance.. mike cutting 11434
