how to identify AF100/090 Tundra coils if buying used

[01t4rnr]

Ive got several junkyards within 200 miles listing various Tundra coils but not sure which configuration (offroad pkg, with Bilstein, access cab, dbl cab, etc) Im think to lift the front around 3" i need a 4x4 offroad pkg which someone has listed for $100/pr. How do i make 100% sure they are the part # ive seen on so many pages?
48131-AF100/AF090 <---- these are what i need

Thanks so much for any help, ready to get rid of these spacers and try a different route. Will be using either OME N 91s or blue Tokico struts

they should be yellow/blue & yellow/yellow paint coded
