That's certainly what it seems like. Would make sense from a production standpoint to utilize one pattern, less expensive.
Update:
Can anyone find a picture/part number/reference/something for the steel plate that mounts the starter in the 3.7L bell?
Update2: I know Clair said in this post that the 3.7L bell requires a steel plate to locate the starter but that confuses the heck out of me considering a 3.7L starter seems to have the mounting holes lined up just right to hit the holes around the starter pocket on the bellhousing.
