Ram 98729 10.00 clutch

I would almost swear mine is a diaphragm clutch, but it was three yrs ago I put it in. I don't understand why they keep telling you these things, the Sd041 is listed as a 10" as well? I only know I saw the clutches listed as 10" when looking a few years ago, someone at that time mentioned they used it with no problem. Cheapest price was on ebay, ordered it, bolted on and went. There is a ton of them on ebay and amazon now.
