FOD in Transaxle?, Metal object stuck between output splines Options

Spoiler Alert! (I am not a trained mechanic).
During a rebuild some months ago, both drive shafts were out for the clutch replacement.
One of the drive shafts was missing the Dynamic Balancer thingy. Allowing myself to be BS'd by the counter guy (turns out it was only half BS) into believing that's how they were, I happily installed it. Well, the shaking and shimmying got pretty bad so I sucked it up, was given the part swap (new shaft still no balancer thingy tho). But not to worry, Toyota was right there for me with $98.00 worth of parts to add on the balancer. (I say only half BS, because new shafts manufactured for these apparently DO NOT have the balancer, or the various steps along the length. it appears to be on solid rod 1.5 inches in Diameter the entire exposed length.
This is where it gets a little odd. long story short the right side axle never bottomed out during installation (the spring clip never gets past the splines). Well, pretty soon, all the gear oil on the driveway (and friends driveways) had me looking under the hood for leaks, and there, viewed from another angle was the driveshaft clearly 17-20 MM out of place from the outputs. the sight convinced me to undo everything and see what the hell was going on.
Take a look at the attachments.

Here we go!
http://imgur.com/gallery/rLrGK Its looking like the end of a shifter fork rod. In one picture at google images you can see the end of the rods have at least one flat on them. its definitely broken off of something, because its rotating 360 degrees with the output splines. the spline bearings them selves have gross play on the driver side.
Looks like we're hooking up the engine support and dropping it this weekend.

It kind of looks like the pin in a limited slip. There's some S54 with limited slip's from the factory. It's common to get the wrong axles from parts stores.

What, may i ask, is the difference in the axles? specifically is there a dfference at the Tx spline end of the axle?? it seems to be bottoming out.
I'll have it on the work bench tomorrow and will measure everything against it's mates.
The auto parts store did not have a differentiation for the "limited slip" configuration of the axles they sold.

Thanks for the reply!
