US buyers, I would like to sell this item to you but since the new tariffs were imposed by your government which makes the shipping to your country very difficult, I removed US from my delivery list.

However, you can buy these parts using the EBAY INTERNATIONAL Hub in which case Ebay will take care of the shipping.
