Don't know about G.C's but 1st generation Durango's just like the Dakota could have an 8.25 or 9.25 depending on the engine. The 2nd generation Durango and the 3rd (or 4th depending on whom you talk to) generation Dakota now only use the 8.25 regardless of engine. The 9.25 is no longer used in any application. The bigger pick-ups are using an axle from American Axle.
