Bill I miss-type, sorry... I hope that you know that I Spoke with SLP is what I was trying to type.
The problem is that the air systems are different on the Series III vs. a Series II header. Two different part nubmers; 30070 for a series II, and 30074 for a series III. Have any of you blocked of the EGR system (I assume that is the Air system SLP is talking about) so if the EGR port does not line up on the header, I think I could just block it off.
