ATS - Kenworth 521 (SMRS Re-work) V2.1

Update 2.1:
- Reworked cables now have two choices - stand and box.

Note: Back up previous 2.0 version if you like default cables so you can go back then to them if you dont like these new ones. Mod name is the same so you can replace  old mod with new version without sellling old truck.
