Might be a very stupid reply, but after such a major accident, is it really worth it to go to all that trouble?

Your best bet would be to buy a complete front end from a 1400 bakkie that was in rear accident. It is however going to cost quite allot to transport to Windhoek. I also don't know if they are going to have trouble at the border with it.
GX grill? Rather forget about that one. They are waaaay to difficult to find.
