I hate to bring this post to the top again b/c I hate to bother people. NumberDummy, when you have spare time could you please decode the code I listed for the 9inch Ford rear-end? I don't know how to do it or if I even can without the books you have. I would really appreciate it.

WDM-AG2 = D6TZ4234D .. Axle Shaft-31 splines.
The 9 inch rear axle has two different parts lists: 88 & 91. Take the WDM-AG2 code, go to (in this case) parts list #88, look for the axle part number that matches WDM-AG2.
Then go to the rear axle ID chart (section 41, page 6), find the axleshaft part number (D6TZ4234D) and Voila! All the specs are listed.
When typing Ford part numbers into websites, REMOVE any spaces or hyphens.
