    What is the best way to confirm this after the old brackes are removed and ground down?

    Kinda caveman-ish, I dont think its the best,
    but I had it close by so I used a cold rolled rod close to the the axle size, staight thru both outer bearings and did some measuring in the middle to check overall, and a nice straight edge along the tubes to check those

    I just want to ensure that I did'n warp the housing when I removed the old brackets. So a simple straight edge will do?

  5. You can check flanges for parallelism with a digital level.

    Set the housing with carrier flange parallel to the floor.
    Measure angle on both axle flanges.

    Turn housing 90*, measure angle on both axle flanges.

    The digital levels are quite accurate and measure down to seconds of arc.

    Did my home-narrowed nine inch for the 31 roadster project this way and it's more accurate than the shop-done nine inch on my 32.

    If you end up buying a digital level get the 2' model and if you need longer tape it to a longer bubble level.

    I have a 4' digital and will probably cut it down one of these days.
