I do not think it would be that difficult. I guess the trucks would have to be coming from Australia , because the South American ones are in its most part younger than 1974. Equador has been making trucks up untill 2002 or so, so there is close ones , but the smog law issues are the problem.
Next time I go there I will find out. The good thing is that in South America many things can happen.....I mean......a 1994 ute could suddenly become a 1974....ups.....

Appendix and errata.....

One thing is sure, anyone looking to get his ute will have to get his butt off the couch and travel. The day I travel to South Africa I will be able to look for a excellent and bring it.
If anyone is going to rely on "someone" to make the deal for him....no complaints about price please......
