So I go looking for a replacement clutch and flywheel for my F150 but there are several options! I see two transmissions listed for this truck and the parts catalog shows a 10" and 11" clutch.

Is there a list of specifications somewhere that will help me identify which one I have?

Its a 1995 F150 XL with the 4.9 6cyl and 5 speed manual trans. The VIN number has a "Y" but no "Z" ....

 

simplest thing to do is remove your old one and then you'll know exactly what size to get. my guess would be you have the smaller size due to the smaller engine you have.
