Brand new hybrid battery - no vent tubes?

I've got a brand new hybrid battery to install from a Toyota dealer - it came with new Gen 4 modules (no lips on the vent nipples, flat surfaces) and no vent tubes at all.

Am I supposed to transfer the vent tubes from the old battery or not?

I need to return the old one to get my core charge back ($1,350).

My plan is to take apart two original hybrid batteries from 2010 and 2012 v, test all 56 old modules, pick 28 best (capacity-wise & load test-wise) and return 28 worse ones (a mix from both years) to Toyota in the 2012 v case.

The concern I have beyond vent tubes - I hope they don't mind module production dates. The dealer says they check the part number. If that's the case, then my plan would work. I even have an old Gen 2 battery that I got from a scrap year for $100 for fun & experience. The modules there were heavily discharged (ranging from 0.01V and 3.279V) - I use them to see how real bad ones look on the chargers. Would be fun if they accept these, but they obviously from Gen 2 since they were produced 20 years ago in August 2004.
