Technical Olds Rocket flywheel ring gear

Does anyone have a source or interchange for the 176 tooth starter ring gears that were used on the 12volt 324 and 371 Olds manual trans cars? I'm thinking about machining up a new billet alum flwheel and may need to find one. I have two original flywheels but would rather not have to pull a used one to put on a new flywheel. They must be available as you can buy new flywheels from Ross, Bendtsens, etc. I just have several chunks of 6061 alum plate laying around and am thinking about making my own.

 

Hello from France ;
i am mill / lathe technician and i made lot of alum flywheels for french cars...
i think 6061 is not strong/hard enough...
i used 7075 for all flywheels i've made...
( 6061 is 95 hb , 7075 is 150 hb )( brinell)

 

I should have a NOS GM/Olds ring gear here..i will look today

 

I'm planning on putting in a steel insert. Is that your concern, clutch wear?

 

yes , clutch wear , and hard surface for the bolts
( hope you understand , my english langage is poor !!! )

 

Nut serts can help with the clutch cover attaching. I prefer them to other styles. They add a little outer weight but hold better torque to me.

 

Yes, I was planning on a Fidanza 1045 steel bolted insert and nut-serts for the pressure plate holes. This is all in the thinking stage at this point so suggestions/critiques are welcome.

 

i agree , with 1045 steel inserts , you are in the right way to go ...

 

Not me, just a card I picked up somewhere.

 

Wow that's crazy. That's only about an hour's drive from my house.

 

If he does not have it, I did find my NOS one today if you need one.
