Updating a very old dimmable light switch

We snapped off the knob on our dimmable dining room light, and I decided to upgrade the whole switch, but canít figure out how attach the older wires to the new switch!

What is currently in the wall has 2 old fabric covered wires coming out of the wall, attached to a box with 2 black wires coming out.

What I'm trying to install is a dimmable new switch that has 2 red, 1 black, and 1 green wire coming out of the back.

Can someone please tell me whether or not itís possible to install the new switch, and if it is, how do I do it? The wires currently in the wall look pretty ancient! Also, how do a connect a new switch with FOUR wires to an old outlet with only TWO? Is this possible to do myself with no electrical experience?

Or should I just hire an electrician to take care of it?

Turn the circuit off. Very carefully pull the wire nut connections out. If you see the insulation coming off.... stop. Leave the two blacks connected and connect to them, Cut them at the back of the old dimmer.

Cap off the green wire and the red/white striped wires.
Connect the black dimmer wire to old white wire.
Connect the red dimmer wire to old black wire.
