I seem to have a split harmonic damper causing some very loud noise when it wobbles back and forth hitting the engine block. Anyone know a source for these, that's less expensive than MSA's 120$ euro damper? A stock one will do nicely.

 

Other than the usual trolling of Pull 'N Save and other yards:
zparts.com has an online inventory, and they're listing various S30 pulleys for ~$45. I bought my '78 vented hood from them and was very happy with the price, service, condition, etc. Now if I could get the rest of the car in as good a shape as the body, then...
good luck,
Dave

 

They do indeed have what I need, at a reasonable price. I think I've confused this site with MSA's (zcarparts.com) before....
