I Emailed Advanced Auto parts all of those numbers and the brand name. Hope they come back with a + answer. What was got me is that Advanced Auto parts is also connected with Parts America which is connected to the Kragen autoparts where I bought my rebuilt axles. The closest Advanced Auto parts (westren autoparts) to me is 176 miles away.
Sent the same info (brand and part number) for those $88-$89 NEW axles to Parts America customer service to day 10-01-07 I hope they will take the time and answer.
