Alpha Heaven in Wisconsin had a nice selection of restorable tanks. I bought a XS650 tank from them a few years back and it was better than advertised. Bike Boneyard in Montana also tends to have good stuff. Dry climate means low rust.
Google them, easy to find.
D&A Classic bikes in Indiana is an Indoor bike salvage place. Most stuff is extremely clean. Phone is 1(260)724-7055. Guy named Dave runs it as a retirement hobby. Fabulous guy to deal with.
The bikes with the frames most similar to the XS400 is the RD250-400 series. If you had one of each frame sitting side by side, you can see where the XS400 design got its start. They are almost identical except for the height of the XS frame for the four stroke engine. Most if not all of the various RD wheels, brakes, swingarm, etc will fit the 400.
