200X experts, what axle is this?

[jrooster]

I recently got an extended axle that was on a 85 200x and and wondering what kind it is. The sprocket set up is way different from stock. Looks to be a plus 6. I found a little blue and orange paint, could be factory or someone along the lines painted on it. Also there are those end pieces that can move over the splines unlike the stock axle.

Dura Blue or Finishline. Can't remember which had the spacers so you could adjust your axle width.
