I have a stack of S4 and S5 front counterweights, and flywheels, both NA and TII.

The real question is, how do I identify what comes from what?

I know the TII flywheels are bigger, but thats about it.

Thanks in advance.

You are my hero.

Now I just have to figure out how to tell my front counterweights apart.

 

the counter weights should also have codes printed on them. but i dont have a nifty link for you

 

Yeh, but did anyone ever record weights/numbers anywhere? I've searched and searched and have not found squat.
