dude,
clean 'em off real good and get the name and size. All teeth are not created equal, you need to know what you have for the replacements to fit the adapters properly.
Think about some pins also.
Fabco has many but not all replacements, 419-422-4533, they will refer you to a distributor in your area.
Hensley will do the same, I can't find the number, go to the website, they are in good ole Texas I think.
Ebay is another, search for bucket teeth.
Get the vaseline out, good ones aren't cheap.
Best of luck,
Martin
