If that's the case then it would appear that the ACDelco part is the best candidate, I've already purchased one, it's going into Tank this weekend. Made in America rather than China, it doesn't seem to be a brand that people have been commonly using as failing replacements, and is very likely to be the same part that the VX shipped with. The persistent problem of failure after failure only seems to be showing up in later years in the forums here, which means the original part is probably better than what people are using to replace it. Hopefully ACDelco is still making them the same way that they made them a decade and a half ago.
