3G Alternator Upgrade/Novi2000 Bracketry

Im going to be upgrading to a 3G alternator. Ill be getting it from a donor car such as a 94-96 Mustang V6 or 95-96 Windstar V6 etc. My question is
1. Are these alternators the exact same size(of housing) as the stock one on my 93'LX?
2. Am i going to have a problem bolting it up to my Paxton Novi2000 bracketry,
or would it be a direct bolt on?

Any help would be appriciated

i dont know about everyone else but mine installed perfectly without any problems on my N2K kit....

exactly its pretty much a direct bolton. I think I have some images of my 3g in my photopost so have a look.
