Hey guys and gals how was everyones holidays??? Well I guess its back to the old blazer we go to finish up last years projects. I have a question about my carb. I noticed that the shaft for the primarys on the baseplate are severely wore out. Now my question is Is there a bushing kit for these or will a baseplate from an older style quadrajet work? I have the original then I have four others quadrajets that are from the late sixties early seventies era with a different style choke. I will include pictures if needed. Thanks for any help.
