I have a 1990 GMC 42 passenger bus with a 366 big block chevy engine married to a 4 speed transmission (thinking a SM465) . It has a 2 speed axle in the back .

Does any one know how to identify it ? And also what kind of oil it takes ?

Eaton ,Rockwell , and Spicer are all the makes I hear . But how do I know what I got .
