You may disagree, but I currently have 3 World Class S10 transmissions in my shed and all of them have a Muncie pattern. All came from 1993 S10 trucks. The S10 T5 with a Ford case pattern you show in the photo is definitely a WC unit. But that doesn't mean that all WC S10 T5s are all like yours. Not trying to be argumentative. Just trying to help folks who are searching for a nice T5 explore their options.
