Yep, should be right.
The rear diff in these cars is sometimes a little off center, not sure exactly why, and it seems to be different on every car. When there were more guys running welded diffs on here, there's always an easy side to pull an axle, some cars could be done without even jacking the car up. EA81s use a narrower track, so you can't use the shaft, but using 4 EA82 cups on EA81 shafts would give quite a bit more extension travel. When I built my Loyale (5-lug, EJ22, lowered), I didn't have any correct roll pins handy, so I used some low grade bolts. Broke 3 on the LH side (actually had a LR axle fall out while driving...) before doing it correctly, never on the RH side.
I have EA82 inner cups on my Brat shafts for a bit more travel. Took a picture last night (Boy does a flash highlight the rust....Minnesota car it's whole life), you can see the extra depth in the joint.
