I'm afraid we don't have an old system which we can demonstrate these on, these wheels are also fitted on many different systems so there isn't a fitting instruction for any of them due to the variation of systems they can be used with. Most of the wheels in this video are push fitted with a barb to hold them in place, you should be able to see the barb in the video. Best wishes - Doorstuff Team
