I have a 55-59 V8 bellhousing but I'm looking for the correct flywheel. I believe the original would take a 10" clutch, is that correct? Is a passenger car flywheel the same as 1/2 ton pickup? Anyone know what interchanges? What about tooth count?
Any help would be greatly appreciated. | | |

The fellow has two, one for an 11" clutch and one for a 10.5". Does anyone know, will an 11" clutch fit with my factory bellhousing, clutch fork, etc.? Or does it make a difference. I'd like to go with the 11" if it will clear everything.
Chevy Duty lists clutches but only 10" or 11", no 10.5". hmmmm...
I just found out that the 10"" clutch was usually used with my 3 spd, Is there any reason why I couldn't go with the 11"? | | |

BTW-my parts man tells me an LUK 12" diaphragm clutch will fit anywhere an 11" will,and is less money. The part # he gave me is 04-064.$148.13-Complete kit. Might be worth a look. Speed | | |

rfs58trk (Fred), a check is in the mail to you for that clutch fork. Thanks again for your help. I may be calling you again sometime for more advice as long as you don't mind. | | |
