    What tranny did this come behind from the factory? I got that rear yoke of the 203 and there was a 32 spline output. Did it come with the th400? I know it had a sb400 stock, from the vin #, did it have a th400 as well? If thats the case, are there more "heavy duty" parts in my blazer just waiting to be found?

    If the "Input" spline count on the 203 is 32 spline then you would be looking at a TH400. I'm not sure about the comparison based on the "output" shaft of the T-case as you have already left the tranny at that point. But I'm not familiar with 203's other than they are full time. /forums/images/icons/smirk.gif

    Pretty sure they all have 32 spline rear outputs.
