I've found quite a few dead threads in different places about this, but has anyone installed a telescopic column in a C5 that was not factory equipped with one? I'm sure I can do it via the FSM, but I didn't know if anyone had done so before. Was it worth it? I've never actually seen a C5 with a telescopic column, but apparently they exist. I'd really like to get the wheel 2 inches closer to the seat...
