What I learned from my turbo failure is that many turbo models have variants. Your shop may not have been able to find the exact match to yours because it is not available in your variant here, but a jeep may use the same model, but a different variant.
my turbo model is also used in audi's, mercede's, jeep's, and other marque model vehicles, but my variant is unique to only non-US vehicles. when I was trying to have my turbo rebuilt, the turbo shop found the kit for my model and said they could rebuild it, but when the kit came in, the turbo oil lines didn't line up with the kit, so I had to get a new one or have them fab it. so it didn't match my variant.
