Need help fast.......Axle bolt patterns

[74Charger]

I am doing an axle swap.  And I just ordered a set of new axles from Moser.  Because the housing I got did not come with any.  I told the Moser rep what I was doing.   And he sounded like he knew exactly what I needed.  But the question of "are the bolt patterns the same " never came up.  Until I got home.   So I guess my question is........Are the bolt patterns the same for a 72' Roadrunner with an 8 3/4 rearend.  As they are for a 74' Charger with a 8 1/4" rearend?

66 to 74 B-Bodys are all 5x4-1/2 lug bolt pattern, But the axles are not the same. The 8-1/4 have
C-Clips holding the axles in and you need to take off the rear inspection cover to get to them.
The 8-3/4 has no clips, the outside axle flange holds the axles in going over five studs and held in
with five nuts on each axle.

Thanks Guys!!!  Thats what I needed to know.  I just ordered a new set of axles, bearings and install kit from Moser.  And a ring and pinion set from Strange.  Can't wait to get this axle swap done!
