I'm sure we can help you get these parts, (heck I've got a hood and right headlight assembly in my garage that I'd love to sell....
BUT
Shipping from anywhere is going to be very expensive. ANDDeXter is always right.. You don't need "Convertible" parts. What you are looking for are standard for all 240sx models.
What I would do is...
1.) Check out NICO classifieds and find sellers in your area.
2.)
