Also, the steering stop lugs on the pre-'71 frame aren't compatible with the lugs on the '71-on lower yoke (the ANG one you have is 850 Mk3) as the later frame has a single stop lug in the centre.

I found a stock front w/single leading shoe and rear wheel. New tires and front axle for 250$. Can’t pass that up. Gonna try the controversial brace too!

A word of warning. If that front end is off a Dominator, there are subtle changes to the Commando drum brake front end. Sliders, fork stanchions and dampers are all different.
Keeping to Commando parts will make life easier for you. Your picture of parts tells me you've got a disc brake front wheel already. Assembling the bike with a drum brake isn't functional thinking! As for the rear wheel hub, Norton's design was sub-standard right up to 1974. I suggest you look at Madass' new rear wheel hub for Nortons (search this site for details), which contains a proper cushion design. Fitting a Dominator rear wheel hub to a Commando will ruin your transmission, as it offers no cushion elements.

Hello. Unless you intend to change the rake of your headstock, make sure you know the difference between 750 style and 850 style ("ANG") triple trees.
You may want to review the frame section in the workshop manual, which shows the early and late frame geometry.

'Make sure' aka 'nein nein verboten'. Mixing down not a yuuge deal, the other way great for more thread warfare fun.

Your frame also has the known weak frame mount center stand, consider going with an updated more robust cradle mount deal.

Agreed. Another worthwhile mod is fitting a pre-Mk3 cradle with the twin cotter pin design as offered by Andover Norton.
I guess your cradle can be modified, but the labor cost may not be worth it.
Furthermore, by fitting a new cradle you eliminate wear at the centre stand connections. I had to replace my cradle because of this.

The upgrade replaces the weak '71 stand lug but as the cross tube has been welded to your frame then you could fit it (and later stand assembly).

Thank you timewarp and L.A.B.
I’ll be seeing that in for sure.
I’ll also be installing that lovely comstoc front spring. That was actually the point of welding the front cross tube on the older frame. I’ll also be keeping the old cross tube if it doesn’t interfere with the newer center stand off the cradle design. I have a newer cradle for this.

Hmmm now that is worth looking into!
Thank you for the link!
I’m taking you word in the bearings dept. as I haven’t messed with that much.
I light be able to get that whole front end at the price of just the upper triple stock!
 
Post up if going with that front end then easier to narrow down part#s, which can get tricky.

Pretty sure that year/model was single disc spoked wheel only, the standard fitting stock wheel is likely only machined on 1 side. If dual disc is important, i would have to dig deeper for a bottom line on this one, then might be easier to find a model that came with dual discs.

Gotta be careful going with ebay info, which can be hit or miss, but for 82 kz750 twin, called CSR Twin - KZ750-M1 for the year, stock deal was spoked wheels, anything not available stock for the year, like going mag wheel is likely easy doable here, not necessarily so to ad a 2nd disc, either require deeper digging tho, to stay with bolt in options or figuring out compatibilities.

for now

You would find better front forks starting in the 1990's and on (imho)
With a Japanese triple clamp fork, tapered roller bearings could be used having an adjuster and locking ring as standard (unlike the Norton triples that need the spacer tube retained and shimmed to length to set the clearance)

I used NSK HR30205J tapered roller bearings. (52 OD / 25 ID)

I ended up getting gifted some Norton triples so I’ll run with a stock front for now. It won’t be forever. Here’s it all bolted up…. Once I figure this out again…
 
So I’m also having an issue where the front iso is coming up short. I’m not sure why. Is there different size cradles?
 
Also I’m having a huge gap with my rear isolating. Anyone encounter this either??

Andover Norton are showing the same parts numbers (cradle and front isolastic housing) from 1968 to 1974 (pre Mk3)
The cradle Isolastic tube is 169 mm wide.

This is why I’m so confused. I saw that too. And thank you for the width.
You can see in the photos how things are not lining up and this has happened once before at Eric’s on a different frame.

I can’t find any rhyme or reason to it.

Dumb question perhaps, but have you verified neither cradle nor crankcase is resting on the plastic box you have put the frame on? Furthermore, I see you have a pin in the lower gearbox bolt position which appears to be resting on the frame rail at the right side. If so you need to remove it. To me it looks like the cradle, crankcase and front mounting just needs a rotation counterclockwise to line up with the front lugs.
