FDS 75 shafts and drop box

I'm looking for TWO inner short shafts for a FDS 75. Also looking for a drop box, not picky about SCS or ProFab. I am building a Mod/National gasses and am still searching for some parts. I know where all these parts are new. Just trying to save as much $ as possible.

Thanks

Found the drop box. Still looking for the 2 short side inners fit the Rocwell FDS 75 front axle.
