B.O.M. Info  Database is done, just need php help to finish.

What is "BOM"?   BOM is short for Bill Of Materials.  Every Spicer / Dana axle came with a BOM.  Use the BOM to search the database.

How do I find the BOM on my axle?  The BOM is most likely found on the longest tube, see Spicer picture. Look for: 6 _ _ _ _ _ - _  Examples: 610048-5 or 603248-5 or 605453-1

"How To Identify A Spicer Axle:  All Spicer Carrier Type axles are identified with a manufacturing date (1) and Bill of Material number (2) stamped on the right or left hand tube on driving axles. The Bill of Material number may also be found on the carrier in some models.  The axle model number will be cast into one of the webs as shown (3), or it can be on the nose.  Each axle contains a gear ratio tag (4), and if the axle is equipped with a limited slip differential, it will have a tag specifying the type of limited slip lubricant to be used (5)." - Spicer cat. 

BOM Database:  Over 6800+ BOM's to search.  BOM database is for axles between 1967 - 2002 (up to 2005 for Jeep).  Includes gears and axle shafts!
        Just waiting for the php admin who is helping me to get done with his move.  No Rush ;)
