The cup holder lug will allow you to adapt your earlier model buggy to accommodate a current version cup holder by replacing the existing handle screws or rivets with those provided in the kit.
This kit comes complete with 4x nuts & bolts plus 1 cup holder lug, the cup holder itself will need to be ordered separately.
If you have a very early model buggy, you may need to have the rivets securing your handle bar to the handle joints drilled out before replacing with the new screws provided. Also if you have a legacy model with a fixed handle (no adjuster buttons) this would not be suitable sorry
Not all handle screws provided will be compatible with and necessary to use on your model buggy.
