I am trying to swap T cases in my Blazer. I have a SM465 trans with a 208 transfer case. I just built a 205 to put in it. The 205 came out of a '78 Suburban with a Sm465 trans. The problem is, my trans has a long output shaft with fine splines. I need a shorter output shaft with course splines to mate up with the new case. I thought all SM465 trans had the course spline output shafts and autos had fine spline shafts. What are my options? Do I have to replace the output shaft?
