Well I got my last 51 f3 home today and to my surprise it has a dually rearend in it. Couldn't tell when I bought it cause of the bush it was in. Just trying to find what it would be out of the only numbers I can find on it so far are ctcaa 4199a a 3 31 53. Anybody now what this came out of? Thanks ahead of time.

 

Your rear axle is out of a 1953 F-350. It's a Timken but I don't know the exact model number.

 

I believe the model number is B150.

 

Thank you gentlemen for the help. Greatly appreciated
