Can anyone confirm that the currently available 3819074 units have the ribs?

Photos, I have looked at these in a while.

ole blue wiper blades
 

These are the wiper blades on this third week of Feb Baltimore 69 if it helps.

The ones from GM don't have the patent number...or not that I saw. I have 4 or 5 set on the shelf & they all have ribs. I would hope you're not going to loose points for no patent numbers....Joe

I bought a pair of the ones in the amazon link above. I can report back when I get them. For $13 I'll take the gamble. Says the estimated arrival is July 17-19 :dunno:

The ones in the Amazon link appear to look like the original "latch lock" style but I'll be damned if I can see any ribs.
Having the ribs appears to be the only requirement for the Legends judging for the refills, near as I can tell. No other manufacturer would have made them with the ribs, I would assume.

Trico 3 is the series. Ribbed is the design....Joe

sorry for not understanding this thread is about current judging standards. Will start another thread.

Follow up. It took awhile but I did get the Order for the Trico wiper blades and they are not the ribbed design. They were packaged in GM packaging with 3819074 on them.
