If you have an autopilot, the old attitude indicator must remain in

Of course that only applies to attitude based autopilots, not
rate-based autipilots, which most of the people here would have (a-la
ones which pull from the turn coordinator - from what I can tell
everything S-Tec, and the KAP140). From what I can tell, in the
market they're looking at, the KFC225 and the like is an exception
rather than the rule.
