Pretty much any Wide5 front kit uses ball joint drum spindles. It's going to be a bare minimum of 1/4" to 3/8" wider PER SIDE as the caliper bracket mounts to the face of the spindle, where the drum brake backing plate was. Then you have the complication of the big, wide wheel mounting area on the hub which happens to be where the caliper goes.
I ended up at at least 3/8" per side, but more like 3/4". The 2" narrowed beam in my car really pays off here as the wheels are where they should be with respect to the fenders.
Louis(LFepardo), is that your first name? It's Airkewld not airkwell
Best of luck to you Bob in your quest.
