9in help

I have this exact axle in my duster. The width is 56” flange to flange which is a little over an inch narrower than a factory 8 3/4.

First off, speedway’s description is wrong. It is not a fabricated housing. The 2nd picture shows you what it should look like. I ended up not using the fabricated housing in the pic because it’s 54” flange to flange.

Let me know if you have any questions. I built mine from end to end several times so I’m pretty sure I have all the answers…. lol
