hey guys. saw a flywheel for sale. it says comes with ring gear installed and balanced at 50oz. factor with 157 teech. ford part number is e2zz6375a and e6zz6375a. the flywheel is double drilled to fit 10 inch and 10.5 inch clutch. my question is how can a flywheel be able to fit a 10 inch and a 10.5 inch clutch. the flywheel can only be one size and not 2 sizes right. just thought id check it out and maybe get some info because i am due for one on my 85 gt which is a 10 inch flywheel.
