I have seen the Shepherd caster guide posted by Everett. It shows a 1 3/8" stem, which is shorter than the 1 3/4" it should be.
Yesterday I went to Motion Industries and found a Colson Caster. But the post is only 1". How critical is the post length. And lastly, where can I purchase a high quality set of casters.
