Rear brake chambers are different with what appears to be 1998 and after. Just figured this out. X24-3276J-10 is the part till 1997 and H20-3276L-12 is 1998 and up. See pics the newer style has wider places where the air lines attach. The 4x4 first gen tm only lists the earlier version the 6x6 tm lists both but does not give any detail about it.
