Thanks to author of the save editor PixelRick
Just use save editor from:
https://github.com/PixelRick/CyberpunkSaveEditor/releases
Or download from nexus.
Move items to the trunk of the car to make them easier to find.
Craft mods what you want to use (duplicadet mods won't work).
Added slots only works once (think what mod you want to use and don't change it). Best way is have max 6-7 mods. Some Epic itmes can have a max 3 slots.
As you can see at the movie, I'm editing a T-shirt.
Always mod last slot for change raw code is the best way. Example this is raw codes for T-shirt
AttachmentSlots.InnerChestFabricEnhancer1 = 00000029956C0E03
AttachmentSlots.InnerChestFabricEnhancer2 = 000000290C655FB9
AttachmentSlots.InnerChestFabricEnhancer3 = 000000297B626F2F
AttachmentSlots.InnerChestFabricEnhancer4 = 00000029E506FA8C
If You have last mod on yours T-shirt - example ChestFabricEnhancer4 just change to ChestFabricEnhancer3 or other from raw u64 hex codes list, but never for the same code. Save game file in save editor and back to game. Load save and you should see a empty slot. Fill this slot with any mod what you want. Save game in game and reload save in save editor. Now you see added slot with mod in save editor what you put in game. Again open last mod and you see - example ChestFabricEnhancer2 or 1, 3, 4 now you must change for another like previous step, but never the same, and save game again in editor and back to the game for filling empty slot with mod what you want.
Repeat for each mod the same steps
