my friend seperated his transfer case and screwd it all up. hes got to replace it and dosent know what kind it is can anyone help me out?? its a 92 2 door chevy blazer 5.7l anyone know what kind of transfer case is in this?

Id bet its a 241c if its a manual shift transfer case.

D-drop 241, very common to find. Just make sure you get the 27 spline input version and not the 32 spline version from manual and 80e equiped 2500's.
