brake equalizer cross shaft

[moasew]

I'm planning to machine the two cross shafts so I can place the split bushing and newer frame bracket on . Is this OK or should I stay with the original brackets and no bushings?

I do not have the individual emergency brake shoes so changing to the single cross shaft would be pricey and take away from the originality more than I'd like.

BTW does anyone have original cross shafts (preferably the second style with the longer tapered socket as shown on the right in the photos) for the equalizer shaft (dog bone)? I need to replace with the same style on each side.
It turns out I have two styles of cross shafts.The very first one on the left and the second style on the right.
