You're in the right place, and you put your request in the correct sub-forum too.
Delica.ca got big enough to include some other Mitsubishi JDMs so we expanded the forum to include the Pajeros and the Stradas. I re-worded your title (in case you were wondering).
Now, to your question: the Pajero is the same body/style as the Montero, just with a diesel engine. If you go shopping around for a '92 Montero windshield, that should fit. You shouldn't have to have a windshield shipped in from Japan.
Another forum to check for parts is
4x4wire - they have a Mitsubishi section which is filled with Monteros and Pajeros.
