GM stopped carrying the replacement part more than 30 years ago.
Around 2000, for example, the Hastings Company (automotive parts rebuild) in my area was shut down and this work, along with other Hastings plants, was moved to foreign lands. Today many of our parts come from companies scattered out through Asia. Quality control may not exist in these factories. America has become an import warehouse. The part "Joe" bought from Classics Parts in 2000 may not be made in the same country today. From what I can gather, there are preferred businesses that pay a little extra to get the pick of the better made "top shelf" parts.
Everybody has their preference. Classic Parts and Rock Auto are mine but just as soon as I say this, someone will come along a bad mouth them.
