Morning: Many of you have helped me with a 9 1/4 axle I have. After cleaning it up I found a number on it and I been trying to use several Mopar based sites to look that number up that is cast on the axle. But every one I try to use all say they are temporarily not available. The number I have is 3723199 or 37228199. Any one out there who can tell me more about this number?

3723199 - appears to be the correct number for a 9-1/4 axle housing which would be correct for a Lil Red. Not much othe info out there.
