Torsion bars

Mine dont have a -5 at the end. just the number. they also have tan colored paint stripe on them. one has one strip the other has two.

Technically I think that stripe is supposed to be "olive", you can see the color codes that were used by the factory in this article.

But that would also confirm that they're .850" bars.
