Wow, I didn't see where you are located.

Must be impossible to get stuff there. Use what you have and what you can get. That certainly changes how I would do it were I in your shoes.
i can import parts illegally and buy paying to smugglers but it cost me about 4 times more than it costs to you , they should bring it with speed boats from UAE ! it's a complete story it self , because i should have someone in Dubai and then ship parts to Dubai and then they must send it to Iran , those mother fuckers wont let you import these parts easily and legally
