Need help fitting cover over door sills. Options

[geetje]

A while ago I bought some door sills, but now I've got a problem.

It seems that they don't fit on a '95 model door sill.
Is it possible to make them fit without modifying the door sill, or do I have to get a '96-'99 door sill?
I've read somewhere that there are JDM door sills and USDM/EDM door sills, is this right? And will the JDM sills fit?
What I've seen from pics is that they aren't different (one model for all), so why doesn't the metal plate fit over the plastic?



Here's what I'm talking about.

On each side of the plate there's a small lip, if I hook that lip around one side of the plastic I can't get it around the other side.

This side goes on the higher portion of the plastic sill.
