On the drive back from vacation the transfer case on my 98 k1500 Burb blew apart. The truck is stuck in Ocala Florida (I am in indiana) and needs 1 of 6 different type NP246s. The ID tag on the case is as follows: 246GM 1500 7093 9 13 97 1 272 I called the dealership and there is 6 different type 246s for that year, what are the differences? Can I make one of the other 246s work? Anyone have a good one? Help!
