difference between eunos & mx5

Can we work up a list of the parts that differ between an Irish mx5 and a jap import.
Very few as far as I can see.
1. ECU minor difference results in 118bhp vs. 115bhp for the Irish model.
2 badges/name
Anyone add to the list
Mazda keeps looking for a chassis no. and then say they have to call Japan even though you may tell them the part is common from 89-97 or 89-93 and so on.
Is there something we can do to resolve the chassis no issue for jap imports?
