Actually the 2nd Gen Ram Cummins CAC hoses are under the battery boxes so the box mounts need to be relieved that is all the passenger Ram Cummins IC pipes couplers and trubo elbow all fit within the GMT400 series.
The Ram Cummins 2nd Gen radiator and CAC fit with minor modifications to the radiator support.
As the grill goes the GM or CHEVY sealed beam mil/commercial grills w/their trun signals etc. work just fine.
Awesome info! Thanks for replying! Will the 2nd gen intercooler fit with the GM radiator, or does it need the 2nd gen radiator as well?
