Kuid Problems

I have about 150 cars and some route that are missing these KUIDs :-1:100073,:-1:10074,& :-1:100075.
I know these are suppose to be built-in. When i check missing dependences these show up as on the DLS but i can't find them anywhere.
Tried DLing the asset but nothing happens in content manager.
40ft Boxcar bogey :-1:100073
50ft Boxcar bogey :-1:100074
60ft Boxcar bogey :-1:100075
If you can help Thank you.
