Anybody with an Olds part number book that can tell me if this flywheel is late or early bolt pattern. It is new in the original box that has basically disintegrated but the part number tag is still good.

Thanks

You can measure to tell.Measuring from outside to outside of each hole, early pattern. Measuring from out side to out side of each hole,early models will have four out of six holes spaced at 2 5/16 apart. On late models only two of the six will measure at 2 5/16 apart.

 

My parts books are at home, but a posting here from '09 by a reliable sounding member states " 68-76 V8".

 

Is it for sale? Id be interested. Thanks Brandon

 

Not for sale.

 

FYI, the site gmpartswiki.com has parts and illustration books on line. There is also a search engine that lets you search a part number like this.

 

Thanks Joe, I have bookmarked that site for future reference.
