syncro U joint question

[TopBud]

I have some vibrations while driving. I inspected the U joint and it's "loose." I need to buy a new one, but can't seem to find one. I can only find a driveshaft, including greasable U joint which is a few hundred dollars. Is that the only option or can I find a U joint that is cheaper? Does NAPA or anyone else carry a less expensive U joint that fits.
Thanks

I was able to find the part at a agricultural parts supply shop cheap also.

Thank You! I wasn't using the correct search terms. I'll let you know how it goes.
