Yes this is all you have to do and these are the parts.. The service manual actually calls for a different part but they were discontinued and these are their replacement. I ordered it Sunday via the website they didnt ship until Wednesday and I received it Friday. Im in central PA and they are about an hour or so east of NYC.
It works fine I didnt order the LED's though so the keypad doesnt light up. Well 123 light up from the S A B C lights but I figure I didnt really need them. It was installed in less than 10 min. I am not sure which LED's are needed but if you do order them and install them they are pretty small and will need soldered to the board. I would not recommend getting them though.
-Anyway you just take the antenna, vol, and channel knob off
-Take battery off
-Unscrew the 2 screws at the bottom of radio under battery and the radio should come right out of the front case, you may have to gently lift up on the bottom with a screwdriver or something.
-then you take the rubber face off the front (it lifts right off.
-put the full keypad rubber pad on
-you will need to take off the the PTT and 2 side buttons which slide right off but the buttons are actually on a plastic piece that has little grooves on the case that they will need to slide into on the new case.
-Lastly slide the new case back on and put the 2 screws back in and put knobs, battery and antenna back on and your done.
