Compare the unthreaded section [shanks] of the bolts. Some bolts used a bushing over the shank and other bolts were machined with the same size shank as the outside diameter of the bushing. Most of the bushings are rusted in place and most folks do not even know there is a bushing on the bolt. Since the replacement plastic cushions come with a certain style of bolt and bushing instead of the larger shank type bolt they are considered as different even though they interchange when assembled. That's the only difference that I noticed.
