I wouldn't bother with pillars in a Tupperware stock. I don't care for the stocks, but I doubt they would really see a benefit from pillars.
On the other hand, the stocks are seldom stress free as delivered. So they do usually benefit from free floating and epoxy bedding as per the instructions others have provided. I usually rough up the plastic and drill it full of holes at the front and rear area under the action for the epoxy to adhere to. Never had a problem.
