Oooooh... Complicated answer is that it's essentially the same shape, but there are a couple of rather substantial differences.
IIRC the tunnel housing is the wrong shape so you would have to produce something to fill the gap, and there is the ever present issue that there is no dashboard on a 110 (well, there is, but it's a ton of plastic) where as on the series 2 it was part of the bulkhead.
now you could cut the old one off, and weld it onto the 110 one, or you could use the 110 dash and some of the other niceties that go with it. (a heater)
Again, the other problem is the windscreen mounts, they are quite different so you would have to salvage the series ones...
Basically, it's possible, but you'll have to do some welding.
