UPC is actually only a label verifying that the product meets the standards set forth by the Uniform Plumbing Code. I hear that many of the older and generic models carry nothing but this label and often use Delta knock-off parts.
I suggest posting pictures of the stem (with the handle removed) on a plumbing forum for help.
Best of luck!
