a903 , a230, a833 , a833od

I can't find my last thread on this . Do all these take the same clutch and throw out bearing ? all cars ion working on are 70-75 slant six cars darts & dusters . Trying to order stuff and things are not as clear as id like. seem no sense in dropping trans and not replacing both. two of the cars are looking to do swaps and 2 cars are squealing bad when clutch is pushed in and several people told me it was throw out bearing. If they are no the same can I get links or part numbers to them ? I love brewers but man I can afford. I'm looking at eBay and Napa. Napa only lists A230 and A833 . nothing for a903 or a833od .
