I am pretty sure you can walk into the dealer and special order a petrol with diff locks, and all the other goodies. I know because I just did that for my diesel double cab, which I wanted in a colour they didnt stock, and while at it, I added the rest of the items (RR + FF diff locks, and a snorkel)
As for the V8 diesel, initially I thought they dont import them here because its to do with the poor diesel quality we have in KSA, but then there are diesel twin turbo V8's on the 200's here, so that doesnt make any sense.
Hey, if South Africa finally got the V8 70, then maybe we're next.
We can only dream.
