A guy came in up at work today (my uncle's shop/junk hole) and needed a T-Case for a '76 Chevy. So I though right away, the 203 laying out back is what he's looking for . Then he mentions casually that is for a manual transmission. I'm going to go out and help him load it, then I realize that he would need a 205. I come back and try to explain this to my uncle and its liking trying to talk to a wall. I am dumba$$ according to him and it will fit. So far I've told him that the shifter will be different, the rear driveshaft, and adapter plate. What else will beong when trying to put in a 203/350 t-case in place a SM465 that would have had 205. I think he just gave the case to this friend of his, so its not a matter of turning a buck.
