A local spring shop could probably bend any size you want, cheaper and you'd probably get it faster than ordering.
That being said any parts retailer online should carry them. I ordered mine off QTM from Georgia.

Also remember one of the front u bolts is bigger than the other because it has to fit around part of the differential housing

I've used these guys and they are great. Just need to make sure your measurements are correct.

I usually go down to the local flaps with one of my old ubolts and go through the ones they have on the shelf. 

Is "local flaps" redundant?

I have bought several sets from Quarter Ton and Military, or QTM. Their prices are reasonable.

Most of those UBOLT suppliers make 'round' ubolts for industrial support of pipes.
Suspension ubolts like Willys used were forged, hence the flattened section that is wrapped over the axle tube.

Just my opinion, but I think that is why so many people break center bolts...

Maybe that’s why Willys refers to them as “clips”.
The m38  and a1 military clips are the longest because of the thick leaf spring packs that were used.

  The original was also tempered. I purchased a bunch of the military M-38 U bolts that are a little longer than standard used on a CJ and run a die to make the threaded area longer to use them on a CJ. It takes a little more effort to thread them because of them being hardened.

I bought from uboltsdirect before and found them to be a good outfit. They say through 9/16" is grade five equivalent and larger is grade eight.
