don';t think so mate, they were fitted to nearly all the dohc sierras mate
you need to find out withy ou ant a 7 inch or a 7.5 inch diff to fit to wehre you want to fit it too though, and the granada has differentbolt fixings to the seirra but nothing that can't be solved
i've got a 3.14:1 dif in mine but they also did a 3.36:1 as well as the 3.38:1 and a 3.62:1 and a 3.64:1 so you need to look for auto V6 granada's if you want the lower ratios
