For the longest time, I was of the belief that all later model NP205s had circle adaptors to the transmissions and that the figure 8s were the older models. Well, I was surprised when my truck, a 1990 V3500 had a figure 8 mount. I figured that someone had swapped it in. (which was weird because the odometer, which matched the carfax report was only showing 60K miles) Well, I was perusing through my factory 1990 V3500 service manual and found this picture. Anyone have any thoughts on this?
