Curious About an Additional Weld Line on a Narrowing

TheGrateRonzini, that makes sense indeed. I'm not a Welder so I wouldn't know a good one from a not so good one......so thanks for the replies everyone.....

In fairness to Moser, I myself took off the Spring Perches and "ground" (or I tried to at least) the remaining weld down....this housing was from a post 72 truck or van as the perches were originally on the top of the axle housing and the vent tube block is down the housing arm and not up on the center section area as I understand 71' and earlier are ?........

I should also say, this was JUST a narrowing job. I thought maybe that additional weld line near the center section was part of a straightening job they may have discovered and fixed for me or something.

I'm definitely satisfied.....%1000....the measurement is spot on so I'm good .....clean it up, spray its new color, an Anthracite Gray and we roll.....I gotta learn about welds....SMILE....
