1976 Big bearing rearend, complete, James Duff axle truss, 4.11 open center section, big drums (11" x 2.25") Small bearing rearend had 10 x 2.5" drums. 66-75 Big bearing rearends had 11" x 1.75" drums. (100 K)
Another view (60 K)
The ends of both axle housings. Notice the small bearing housing has a rounded bottom to it. BIG DIFFERENCE in the backing plate/bearing retainer studs/bolts!!! The big bearing uses 1/2" and the small bearing uses teeny tiny weeny 3/8", jeez didn't seem safe at that point to me.... (45 K)
Another view (56 K)
Big bearing end vs. small bearing end. Notice the small bearing end is the same diameter as the rest of the tube. (34 K)
Big bearing
axle (28 spline) vs small bearing axle (28) spline (77 K)
As above, but more
of the axle shaft, notice the larger portions on the big bearing axles
(78 K)
As above, bearings,
bearing retainer plates, notice the difference in hole (stud) size.
(59 K)
As above, you can see the thickness/taper
difference between the small and big axles. (68 K)

It uses a hex head recessed. I believe I used a 1/4" pipe thread tap, very common tap, very common hole, very common fittings. In fact, I used it for the intake manifold tap conversion too. The tap is a tapered thread tap, so you don't want to go all the way in (otherwise you wont ever get the plug tight, it will just thread all the way into the housing.)
The very bottom of my 9" is covered by the axle truss, so I put it slightly to the side. It is protected by the axle truss too, and still drains the whole axle with a jack on one side to the other (back and forth once to get all the old oil out.)
I left a little oil in it when drilling and tapping (the center section
was out anyway), but this way the oil comes out by gravity and brings the
drill shavings with it and cleans the tap as well. Kinda messy though,
but I didn't care. Just make sure you test the plug several times
so you don't tap it too far. I use teflon tape also. Hasn't
leaked yet and worked great the one time I had to drain the fluid.
Can't believe I didn't do this years ago!
