Mini-starter compatibility

I just picked up a mini-starter for $16 at Pick-n-Pull from a 1994 full size Dodge pickup with a 5.2 - I see most guys are grabbing them out of mid-90's Dakotas and vans. I can't imagine that there a compatibility issue with the full size trucks but weirder things are true sometimes. Anybody out there have some knowledge on this subject? Thanks.
