Actually, there is some conflicting info here.
There is no need for the 03 carrier, the 2002 carrier will hold the axle just fine, it just requires the need for the 03+ Blaster brake hub or ANY Shee brake hub.
And, NO, a Shee carrier will not bolt up to a blaster...
SO, to reiterate:
88-2002 Blasters will hold the Shee axle fine, just requires the Shee brake hub to re-fit the rear brake properly.
