Thanks a lot NAPA :(

Lucky it's just the bolt ... if you had to return the booster to NAPA and it was a special order, every NAPA store I've ever dealt with had a 10-15% "restocking fee" they charge you even if they're the ones who messed up and ordered the wrong part.

A bit off topic, but I for one miss the old days of friendly counter staff and getting the right part the first time. When they all started relying on computers rather than catalogs, we all now have to rely on the accuracy of the typist on their end.
