Back in the day I ruined a couple sets of axles and wheel wells. I would never weaken the axle nowadays with plenty of big bolt axles available aftermarket. Talk with Dr. Diff.

You'll still have the small center register, so no wheels will pilot, and you'll have oddball drums. If you're bucks-down, just take a chop saw to C-body or pickup axle shafts.

Can any C-Body axles be cut to fit the A-Body 8 3/4? How much needs to be cut? What year trucks? I have re-drilled A-body axles right now, but would like the big register. I would still have to use the A-body drums and re-drill them, right?

No, you'd use brakes (complete) from any "big bolt" 8-3/4" (or even 8.25 / 9.25" with the same bolt pattern).
I used to have the data showing which donors had enough spline length to cut, but I cannot find it. Hopefully someone else will chime in.
Also inexpensive new axles are made specifically for this swap (Yukon, etc.)

Like I said above after losing a couple redrilled axles (your use may vary) I sent a pair of C-Body axles to Moser to have them cut and resplined (this was in 1980) and used the 11" C-Body brakes and never looked back. Now that there are plenty of ready to use axles I would go this route today.

Drilling and tapping using screw in studs leaves very near as much meat around the stud as the OEM original knurled pressed in studs

The axles on my sons Dart were drilled to the large pattern and has screw in studs. It was done in 1997 and the axles are still in the car. It has been raced and driven over the years with no problems. Ron
You guys need to quit making sense.
I've done the same thing. Launching off a transbrake and running sub 1.50 60's.
Run stud centric wheels.

Too close to the edge, I'm frugal and would not even consider it after looking into it.
Pick up some truck or a set of C-body axles and have Moser work their magic or if you are a fan of sealed bearings (I'm NOT) get some aftermarket axles.

Not if you usse screw in studs. There is all most as much meat around the stud as the large holed knurled type. You will break a stud before you break the flange.

No. There are only a few years in the early '70's that will work, and they are usually in a C-body wagon. The only way you can tell is that just past the splines will be the same diameter at the splines. Most are a smaller diameter in that area preventing them from being resplined.
