The rambox bed divider from any DS model will fit any rambox DT model. I'm assuming there are different part numbers because there are slight differences in the dividers (such as number of horizontal bars), but those differences don't affect fit. The swivel and grommet are a simple install. Just remove the plastic pins and screw them in place. I suspect that eventually they will change the design, and will not provide the mounting options for the swivel and grommet, but for now they are still building them so that we can install them.I have an opportunity to pick up the 68027145AC. Dodge parts is telling me that the part went from AC to AD to the current AE. The part itself should be the same. There are many reasons why they changed the part number. Some are 1) the manufacturer changed or simply tracking of a product number. etc.
DDJR - few questions for you:
1) what model year ram do you own?
1) Did you end up getting the AC and did it work as intended?
2) Did you purchase the swivel (68054996aa) and grommet (68054997ab)? If so was the install straightforward?
