Torsion bar question...help!

I think I have a bent bar on the Scamp. It looks slightly bent to my eye when I roll it on the floor. I have another set of bars from the Demon. But there are some differences in the markings.
The Scamp bar is:
891L / UXD on one end and 891L / 330 on the other.
The Demon bars is:
891L / UNL on one end and 891L / 142 on the other.
Are they the same bars?
