I would think so. They've got all sorts of stuff like that from multiple manufacturing sources.
Our Bronco vendors sell that stuff too however. Borgeson and Flaming River are pretty well-represented these days.
If yours is just like the earlier manual shafts, with just a straight shaft and that little "tulip" joint at the box, you'll need a u-joint that's splined on one end and set up for a set-screw or something similar at the other. Since you don't have what's referred to as the "double-d" shaft, you have to take more care in anchoring the shaft.
You'll also probably have to cut the shaft shorter to fit the larger joint, but it should work. I'm a fan of additional welding, but it's not officially recommended because of seals in the joints and stuff like that there.
Are you ever planning to go with power steering? If so, now might be the time while you're figuring out all the proper geometry and parts for the u-joint. That way you don't have to do it again when you change boxes.
More work for sure though. A joint by itself would be the quicker solution if this is your daily-driver.
Not sure where Ruskin is, but I've got at least some of what you need here in the garage. I picked up a Spicer yoke and u-joint awhile back, but ended up changing my steering box to one with a different spline count. I think you'd still need the second yoke (for the shaft side), but that should be available through a Spicer parts supplier too.
If you're not local to me though (which I assume you're not), you can most likely find what you need from a local supplier too.
Good luck.
