If you don't care about it having the chrome lock strip, either will work. The base kit has a black lock strip as the difference. Looks like your stock one was at one time chrome as 1774btcrew said, but the chrome may have flaked off or faded if it's not currently actually appearing as chrome. If you're not sure what the "lock strip" is, it's the piece of plastic that you jamb down into the center gap of the windshield's rubber seal to hold it all into place.
