The front axle in the 110 is further back, and the back axle even further back than on a 109. Not sure of the numbers, but I think the front axle is more than an inch further back.
But as commented above, except for the wheel arch all the panels are the same dimensions from Series 2 to current Defender, and are interchangeable subject to changes in design and detail fittings, so you might have to do some adapting.
This does not apply to the 88 versus the 90 - not only is the wheelbase four and a half inches longer, but the body, and hence the tub and everything else is longer too.
