Went to the hangar and grabbed by build manual. It calls out the 27002 as flaperon ribs or "odd number" ribs. After reviewing the document, it looks like the builder adds the upper and lower cap strip rib reinforcement at the rear spar at step 12.
Sounds like they only use one part number now.
You might want to check the web thickness as previously mentioned. Put the thicker webs at the hinge locations, with the re-inforcements and you will likely be ok.
