I have been swapping out my now cooked 305 for a 350 and when I pulled my clutch I was amazed to find it was cooked as well. This is amazing to me cause it felt perfectly fine and I figured it was somewhere around like half worn not just gone. Anyway the only clutchs I have in my garage are too big for my pressure plate. So I went to Autozone to pick myself a shiny brand new clutch. I did so but forgot my old one for the core. I went to put my new clutch on(which happens to be the last step before installation of my freaking engine) to find that this clutch is the same too large size as the ones I have. I think mine is about an 11" clutch plate and the ones I have and was given are 13". Sound about right? What size is stock? Did they just give me the wrong clutch or did someone before me change the setup?
