Theres no listing for Carrier, instead, looking at the diagrams, I would assume
Chrysler are using the term "Case Kit, Differential".
So you'd need to verify that with them.
Can't see any differences noted for bearings or shims etc, only the Gear Kits & Case kits.
They are marked as I noted earlier: DMC =3.21 DME=3.37
2009 Front:
68019 333AB [DME] Gear Kit, Ring & Pinion [3.73]
68026 549AA [DME] Case Kit, Differential
2008 Front:
68019 333AA [DME] Gear Kit, Ring & Pinion [3.73]
68026 549AA [DME] Case Kit, Differential
2008 & 2009 Rear:
68038 761AA [DME] Gear Kit, Ring & Pinion [3.73]
Regarding the Case Kit, that part number refers to the box marked 76.
EDIT: have you talked to Wooders, or some of the other site sponsors to see what they can supply?
