[s-cars] Was Bad CPS - Now Bad Crank Pulley

[Tom Green]

Darin,

I take it that the actual parts for the harmonic balancer were not  
the reason for
the $600 parts estimate Dave has?  I wasn't too clear on your post  
about only
changing part of the balancer.

Couldn't you just take some of that rubber cement that you can't get  
off your
hands and re-bond the rubber parts to the hub?

Tom
