My Indy MB mechanic says that ackits dot com must be selling poor quality parts because their price is cheaper than HE can buy them from his supplier(mostly worldpac). Has anyone used actkits parts? If not, where is a good source for quality parts at a good price? My evaporator on my '92 300 2.5 TD just crapped out and I'm getting hot. I need evap., drier, ect., ect. TIA Ernie in Louisville
