Need help wiring 3-way light switch dimmer

Hi-

Can someone please verify which wires from our old 3-way non-dimmer switch go to which ones on the new 3-way dimmer switch? I wasn't able to piece it together and don't feel like burning our house down.

Thanks in advance. Pictures attached. New switch is Lutron.

Did you read the instructions for the new dimmer? Look at the old switch and you will see it has common written on it where one of the black wires is stabbed in. Use that wire on the new dimmer where the instructions state to connect the common lead, most likely the black wire. The two red wires on the new dimmer most likely go to the "travelers", the wires on the old switch that are not marked. The green wire on the dimmer connects to the bare copper wire.

It's marked on the back...... common goes to black on the dimmer.
The other two make no difference.
