Wheel bearings are the same as every other cruiser since way back
Same bearings means same spindle OD, so its just a "unique" wheel hub...

Yup
No reason to change the hub, just use a new drive plate broached for 32 spline, and add your own method for retention (more dowels, larger hardware, etc) No reason to add more cost.
All parts we have here on the shelf...
IMO there simply isn't enough room on the 8x Series rear FF hub to drill to the larger 7x/10x drive flange/axle pattern and going with a bigger hub body diameter will require different wheel solutions in some cases.
Hard to tell from the pic but the edge of the 7x/10x pattern is literally the outside diameter of the 8x hub shown
Wheel bearings are the same. I'll have to pull a 7x/10x FF rear hub and compare it next to the 8x hubs we have here. While the wheel bearings might be the same, it's entirely possible the length and flange location changed. Will have to compare when time allows.
And that is totally doable, we have customers buy the bigger 10mm hardware and upgrade their existing hubs (or use the SAE stuff as discussed a few pages back). Of course that is basically this kit: Nitro Pro Series Chromoly 32 spline Upgrade Axle Kit
Yep that is exactly what I want, but from RCV and not Nitro given my track history with Nitro rear shafts. lol.
Question did the 105 get bigger brakes front and rear, or was it 80 brakes?
Late style hubs have to be bigger OD in order to accommodate cone washers on 10mm studs (bigger OD is slightly better at handling torque). Studs are unquestionably the correct way to fasten that joint, but I am not willing to change the hub on my axles I'll machine to suit.
When making custom "junk" and strength is the design impetus I always use the biggest hardware that will fit the space, between standard and metric (caveat is needed clamp load; think thread pitch). Since the mode here is strength I'll run fine thread, but its less desirable to me in
spots that can be contaminated with dirt (fine thread is sensitive to debris, but offers a higher clamp load)...
10mm = .393" x 6 = 2.362 of cross sectional thickness (on a slightly bigger hub diameter)
7/16" = .437" x 6 = 2.625 of cross sectional thickness (on slightly smaller hub diameter)
M10 x 1.25 (8.8) = 40.5 ft lbs (55 NM)
7/16-20 (grade 8) = 55 ft lbs (74.5NM) (remember the hub is cast, sticking to grade 5 torque spec here)

That was my memory.

Yep bigger diameter discs, thicker disc, larger surface area on brake pads.
Offset from hub flange to disc is different

Spindles are the same.
Brake rotors have a different offset to 80s, but I can't remember if the hub has a different offset
How wide?
How much weight is saved, and how much drag is really lost versus the risks of not running two? Serious question, because when you're talking about a beast like an 80, is that weight saving even noticed?

Rotating mass is much more noticeable than total mass.

X2! - 32 spline kit from RCV
But one needs to plan. Maybe its that instead of electricity for the month!
He's kidding. You have to run 2 bearings.
