I search all of the web and everyone that has some type of Rear End decoder points to the decoder page on the americanclassic.com website. It is very helpful as I found out that the year of the truck the guy told me when i bought was wrong. He claimed it was a 51 but by looking up the serial number turns out it was a 49 so that is a plus. Well the guy claimed that it was completely orginal, motor, tranny and rear end. Well one clue that wanted me to double check the rear end is no rear end chunk, no housing cover plate, no drive shaft and there is a bracket like there would be a tube shock that would bolt up to it. By look at the numbers I found and looking up 49 on that site there was no match. I also keep going through their list and no match for BBA. From my brother-in-law, a ford person, and what I read about 9 inch ford it's not one as this rear end doesn't have a taper to it.
Information:
Rear End Housing Tube: Has BBA 5 11 W with the letter D below it
Rear End Housing: Has the Letter N with the number 3838227 below it
Rear End Housing Cover Bolt Holes: 12
Link to some pictures of the Rear End with a few extra pictures Any help would be helpful so I can know if this is a good rear end to keep with my plans for the truck or if this is something else to put on the to buy list.
