what's the tube Dia on the Mono Beam? Also do these knuckles fit the large F-550 axle and joint? I can't remember what the benefit of the F-550 stuff was.

Yes, these use the big huge ball joints, bigger than 250/350.
Lowers compared:
Uppers:
Outer knuckles:
Inner C:
8-lug UB on 550 knuckle:
(8-lug UB does not come with the axle, 10-lug does.)
Axle tube dia. On the 550 mono is 3.75, tube thickness is about .370. (A hair less than 3/8)

The 250/350 axles run 1480 joints. (Same as "standard" 60's.) 1480 shafts will fit these knuckles. But the stock f-450/550 4wd platform used 35-spline 1550 shafts. The cool thing about the 550 knuckels is that there is enough space inside of them to fit a rockwell joint or a rockwell-size RCV joint.
So you could run standard 1480 stuff. But it would be a shame to do so when these knuckles lend themselves to so much more stuff that is so much bigger.

What spline shafts come in the 80? Are the gears gone or just broke?

Have not pulled a shaft to see but should be 35 splines.
The gears in it are damaged but not exploded to where anything else is damaged. It's just the tips of a few teeth. I don't know how that happens. The 5.38 gears I have are new.
