Hi Emmanuel, welcome from Scotland.
I see guys in Oz can have similar problems sourcing parts as we do here in Blighty!
Are you sticking with the Mitsubishi front end?
In saying that the Stovebolt Forum is a great place to find some obscure and rare parts,should you need them.
Plus they're really a good bunch of guys(and gals!)
I look forward to the pics.
Jock.
