That one looks like it uses as extension housing and a stub shaft that plugs into the original universal joint. Wouldn't it be simpler (and shorter) to just use the front half of the torque tube u joint with a flange that bolts to it, since the replacement housing doesn't pivot? That would also eliminate one source of vibration and possible failure.
