I have no idea.
I want one for my Escort, someone who has a sierra has one going spare.
Thats all I know.
I just though, well it's a Ford... they are all as bad as eachother so it might fit, maybe with some new holes etc
Good point about difference between the drive, although I have no idea how that would affect it.
Maybe it's just best if I go & look at it, try it for size.
Cheers.
