Some time ago I purchased a 3 inch drop axle for my 3100 I am just now getting to put it in I bought a standard king set from checker's but the lower bearing is a quarter inc to thick when I went to call the place I bought it from they had gone out of business. Has anyone else had this problem? I know I've seen a place online or in one of those catalogs that sells the axle maybe if somone knows they could help
