When you try to take the body off, set yourself up with about a dozen round toothpix. As you turn it over to pull the carbody from the undercarriage, place a toothpick in the gap as you go down the side, it'll take about six. Do this to both sides. Then turn it rightside up and the body should pull away from the frame fairly easily. If not, one or two of the body clips are still snagged so just repeat the toothpick dealy 'til it does come apart. Room for the chip can be found above the passenger compartment. While I did not do it on mine, I understand that more room can be had by removing a brace from the window casting. I love my doodle on DCC, the ability to turn the lights on and off remotely as well as the overall smooth mech makes it one of my favorite runners.
