RAM 1500 from 99 with 164KW ? Search for the TSN in vain

Moin moin together, I have a question regarding a key number for a Dodge Ram. The vehicle was imported by the previous owner from the USA and therefore has as type key number 2 only as so often known zeros. However, if I enter the first registration date of July 1, 1999 in the car letter and in the search 164kW machine I get the notification that this vehicle was built only until 06/1998 in this version. I suspect that the vehicle was built 98 However, I still lack the key number for 2 as repairs have to be carried out. According to Google, the 5.2 L V8 with 164KW has only been installed until 06.1998. In this respect, there is now a small puzzle and hope that someone can help me further. I look forward to your answers Best regards Sascha PS: I am looking for a side window front passenger and for a C1500 Stepside a gear converter, if Since someone can help out please PN to me. Thank you very much
