It appears so. The gear on the right side of the pic should slide out of the housing. That is the one i was referring to as the slave, as it's practically driven off the other one. Anyway, that should make your measurements clear.
I just noticed your pump has a 'B2' stamped on it. My GTE has 'A2'. Perhaps its a code indicating it's gear sizes..?
And i see another difference. My pump has the five bolts for the bottom cover, plus two dowel pins to hold it aligned...
