I'm not sure if understand you correctly. The sierra was also produced / manufactured In South Africa. I don't think vehicles were exported from northern hemisphere as a product to be sold in South Africa. Ford SA probably used certain model designs for sure but components were sourced and produced by Ford SA partners from our local market as well as sourcing components from Europe, Britain, Australia etc . at that time.
I picked up a thread where that same diff could be a BorgWarner design / production, but I can't find any detailed history or specs using the diff part numbers. They are both M71 diffs
I think when I open them for a quick inspection might reveal some more secrets
Cheers
