I can't recall that my 64" springs were wider, but if they were, it wasn't a problem.

64" springs. How is this done? Lift amount? Etc.

Your thinking of installing a set of rear springs up front
They're stupid stiff Superlift dampers for a Furd with an 8" lift I got off eBay from Superlift when they used to clearance things out on eBay... for $9.99. I still have a bunch more of them new in box, they're still so stiff you can't move them by hand. They were temporary to try to stop the Interco bounce when going down the highway at 55mph. Worked well enough that I never bothered to do anything about it.
The long story is that it was supposed to be a build that was cheaper than the tires I put on it and weigh under 2500lbs with me in it for snow wheeling... and zero tube to make fun of all the Jeep people that spent all their time bending tube and putting Chevy parts on their Jeep. I think I paid $1700 for the 44" TSLs new to my door a dozen years ago and when I bought brand new Tuff County 56" springs it barely pushed me over the $1700 for the rest of the vehicle. It is exactly 15' long and has exactly 10' of leaf spring.
It has been sitting with a tarp over it since 2007, this picture is from 2010, the last time I trailered it somewhere.
This is the frame with most stuff removed, the only thing that stayed in the original spot was what you see EXCEPT the engine crossmember had already been moved:
This is how I drove it for a while, with 40s, kept getting hung up on the factory crossmember even though I clocked the transfer case flat so I later built a new one so I could have a flat skid plate. At this point I had paid for the tires and wheels ($700+300, used), the rear springs ($100, used), 4 new Superlift shocks ($40+ shipping), a pair of steering knuckles plus machining ($125), a steering arm ($50), a clocking ring ($50 but it was a trade), new brake lines ($80ish), and a couple of Superduty shock towers ($19 each I think). Everything else I already had. I did end up buying new lift springs for the front after destroying 4 sets of factory 56" springs and I destroyed one hydraulic bellhousing.
In 2007, since I hadn't managed to break a shaft yet (the only thing broken to date is a bellhousing) and I hadn't put the D60s under it yet, I bought 44s for it. At this point it has a TBI 350 out of a G20 van because the TBI 305 I had forgotten I hadn't drained the block (straight water) when it froze one night in September. It could actually move pretty good with a TBI 350, was fun to burn donuts on US41.
Shortly thereafter, I got a new job in Wisconsin and it has been sitting ever since. Things were different 15 years ago.

spring width the same.
Leave the springs bolted to the axle and the hangers bolted to the springs. Roll the axle forward where you want the tires to sit, bolt front hangers in place. Then move to the rear
@Abusfullofnuns correct. I didnt move the crossmember
There is a point where GM went to a 3" rear spring in their 3/4 ton trucks. I want to say like 2011 or 2012? When I was junkyard shopping I figured it out the hard way.I was thinking I read somewhere that they were 3" instead of 2.5".... I may be confusing them with different ones though
Now 1/2 tons might of stayed 2.5 not sure? I was only looking for 3/4 ton rear packs. I have 1/2 ton 63" rears in my k5 currently and I think they are a little too soft and also the leaf below the main leaf is considerable shorter in length, kind of creating a weak spot if your flexing them a lot. With 1 trail ride on mine the main is already bending. I will be putting the 3/4 tons in soon. The 2nd leaf on them is just slightly shorter than the main, hopefully will be longer lasting.
On mine, I got a 2nd pair of spring packs, cut the wraps off the main leaf and added those under the main leaf of the other spring pack.
Traction bar was a must offroad.
Both spring packs i was working with were from a very light duty truck. I think they were only 2 leaf plus an overload. So I added the 1 leaf to the pack and I added a 1" zero-rate to match the front. I had 52" springs up front. Eventually I removed the overloads from all 4 packs to lower the truck a little
