Yeah it does and I kinda like the way mine looks. My motor plate can accept a regular starter as well but I like the top mount and haven't been able to find one.
Life is uncertain. Don't sip.
The 3-bolt flange is similar to top mount, HOWEVER, a top mount starter is reverse rotation. The armature is splined reverse, and the field is polarized backwards vs a 3 bolt flanged 'truck' starter. the 'throw' of the pinion gear is about .100" to .150" longer too.
If I remember right, look for a 'top mount prestolite' starter.
