He has a stock clutch and wants to replace it but he says there is a problem > > apparently he says stangs came with two size flywheels, a smaller one and a larger one. he has the smaller one and the clutch is for the larger one. But there are also 6 bolt cranks and 8 bolt cranks and he doesnt know which one he has, and i guess that makes a difference > > Any input on what crank he has? well the clutch should be the same on both if they are getting a new flywheel they need to figure out where the engine was built. 6 bolt = romeo 8 bolt = windsor hope this helps --- _[View the full topic](https://forums.speedlife.net/t/mustang-guys-need-help/187721)._
