SOURCE: Hyundai 2006 Sonata high mount brake light. the rear seat does NOT have to be removed in order to replace the stoplamp and/or its bulb. you have to get into the trunk, and there are (2) philips screws holding the stoplamp secured to the package tray. the actual process takes about 15 minutes, because to do it right you have to actually get IN the trunk. These heavy duty replacement bushings from BBK are constructed of high quality durable urethane. These bushings will help to improve handling and traction while also giving your Mustang a tighter ride quality. *For use with BBK rear control arm part numbers BBK2521 and BBK25210, as well as control arm kits BBK2526 and BBK25260. If it was "replaced", it would require the control arms to be disconnected and reconnected. If it was only "modified" there would have been no disassembly of the control arms required. See the picture below. The picture shows the rear suspension parts. Notice that the upper control arm and the lower control arm bolt to the trailing arm.
