Piston Ring Set Question

I'm rebuilding and resealing my Engine and am looking for a few more parts.

12033AB010 is the part number I found on OpposedForces.com. for my car. According to my Local Subaru Dealer, Subaru no longer makes this set of piston rings.

Is there an alternate part number? Since Subaru's 2.5 liter Engine design has remained largely the same for 00-07, would part number 12033AB340 fit my car?

Thanks for the help.
