Not only are these a good replacement part for worn parts. But also it is always a great idea to have some flange tubes lying around. You'll never know when you might need them as a spacer or even a custom DIY. I have used these to make adjustable camber on the original Tamiya TT02. If you couple these flanges (x2 packs) in the empty hole where the old I upper suspension link was, and if you fit 3x16mm screws per side and some 5mm pillow ball nuts you'll have a mount to install an adjustable suspension link to change the rear camber of your TT02. Great part!
