N54/n55 bellhousing bolt patterns

Hey I was wondering if n54s had the same bellhousing bolt pattern as n55 cars, at least early n55s? Looking at engine swap parts for an ls conversion and all the swap bellhousing I see are for n54 equipped cars. I know the transmissions are a bit different but is the basic bellhousing the same?

The bell housing bolt pattern is the same between N54, N55 and S55.
