Can you give me the Guzzi part numbers please and I'll look them up on my parts guide .pdf. I see MG is out of stock on the clutch kit. How about all those clutch tools MG has....are all those really needed? Thanks

One bearing needs to float, so the spacer should be long enough that one sits flush with the carrier and the other fully inserted.
Here's the dual o-ring outer body: https://www.mgcycle.com/index.php?main_page=product_info&cPath=193&products_id=4793
Clutch from the source: https://www.stein-dinse.com/en/moto-guzzi-clutch-set-with-locking-plate-new/item-2-1078679-200033302+-.html Unfortunately, it will be hit with tariffs... Might be back in stock at MG Cycle and Crusty Cycle soon though.
The tools aren't absolutely necessary - you can use the clutch hub (with a suitable spacer and bolt) to align and compress the clutch plates.

Thanks Charlie. With regard to the front wheel spacer, here's what I did. I purchased the recommended spacer from McMaster-Carr suggested by This Old Tractor and had my buddy cut it down to the correct length posted by Gregory. I got it home and went to install it and, because I'm a Guzzi noob, it appeared too long so we cut it down until we could get the newly purchased snap ring to fit. So it sounds like you're telling me the original spec would be good, remove that snap ring and go with that. I bet that's why my axle hole on the right side was partially covered when it was tightened down......that would make sense as it was drawn too far to the nut side when tightened. With all the things I'm finding mechanically incorrect with this bike I assumed some one left out the snap ring, since they left out the spacer.
Any alternative tool source for the clutch hub nut? That's a real bite paying $60 for a tool you won't use often.

Sounds like a great project. Good Luck!
Pictures always welcome for those of us following along.

The dimension (76 mm long) on This Old Tractor is correct. As I wrote previously, one bearing will be fully inserted and secured with a circlip and the other will be flush, or nearly so, with the outer edge of the bearing carrier.
You can make your own clutch hub nut tool - an old socket of the appropriate diameter and an angle grinder or even a hacksaw. Or modify a tool purchased on Amazon to work as shown here:

Here's information on the bolt size needed to use the clutch hub as an alignment and compressing tool.

Thanks again Charlie. I ordered one of those tool from Amazon that was recommended on TOT, and I'll dig into the other link you sent.
Getting back to the front axle spacer. What was Guzzi's thought process with regards to the left bearing being a "floating" bearing? I took the front hub apart yesterday and the spacer my buddy made came out to 70.22mm. My buddy Gil was with me and I decided to just make a 6mm spacer from the leftover McMaster-Carr tube and reinstall it. Gil asked why couldn't we just leave everything the same, bearing in place with the snap ring like the right side, and put the 6mm spacer on the outside of the left bearing? This will allow the front axle to still seat at the proper distance.....unless Guzzi decided the wider stance of the bearing is needed for stability or tracking reasons. Thought's?
