Hi
I have a turbo 400 trans and my driveline on the yoke has a harmonic balancer on it and my driveline also says balanced on it.The question is dose any one else have a harmonic balancer on the yoke?
Thanks
Jaime

Hmmm? Can't say as I've ever run across this?
I've had many TH400's in many kinds of GM vehicles and have had a few drive shafts built, and balanced. But never run into any kind of Harmonic Balancer? Weights... but not a Balancer?

Sounds interesting, but bulky?

Maybe Quenton, or Tom, or someone might know more on this?

Later - Brett! - 67 Drop Top 455!

I've seen them, but never on a Pontiac - at least not a GTO or Bird.

Likely a later trans and driveshaft modified to fit your bird..
