Thanks!  
As you can guess, I try to make a replica of a friend's 1:1 Peterbilt.  It's the reason for these number.  There's few others to put on, so I will try to improve my method for printing them or find some already printed...
For the Bruder, I got it with a Mack and a trailer that I want to rebuild (and stretch) to adapt to my KH.  Maybe I'll work  on the Mack later 

.  They are really pretty toys!
