Ram 98729 10.00 clutch

Not sure what to tell you. I ordered the clutch SD042 listed for a 65 273 off ebay. Bolted it onto my factory 9.5" flywheel ( might have had to change to an allen bolt), and have at least 3k carefree miles on it. It fits. I just found the invoice, bought it in 2013, says 10".
