I recently bought an 83 blazer. Originally had a 305, now has a 350. Originally had a 700r4, now has a hydromatic 350 that needs replaced. BUT when i pulled the tranny/tcase today, i noticed it was a solid rear yoke. The front shaft has the double ujoint mount. Last i knew 208s have a slip yolk. My buddy with a 79 fulltime 203 said mine had the 4 selectors and not 5. So what could it be? I will have pics around noon tomarow when i get out for lunch from school.
