it doesn't seem to say how thick or how long the piece at the end is. The door hinge fits a 3/8ths bolt, and you'll need about 2 inches of bolt to stick through the hinge in order to still have thread room on the bottom to get a nut on there.
From looking at that image, I would take a guess that no it might not fit, since the bolt at the bottom is might be a little to short. Hard to tell for sure though.
I'd go to an auto parts store, or a motorcycle accessories store (Harley store?) and check out the mirrors they have there. You'll be able to look at them and see how long the bolt is.
