I can make you stands like that, but why? Those are an old style for karts with narrow rear bumpers. The newer style stands that we make are for both full width rear bumpers, and standard ones. The only reason to buy one like you pictured is if you have a low roof and you need to get the kart as low as possible. I also make a double version of these stands that stores karts bottom to bottom, as well as a hanging version that hangs the kart from the nerf spuds and not from the axle, which can be a problem with soft axles.
Give me a call or email at the shop 877-777-8020 or firstname.lastname@example.org. I can let you know what the options are and get you setup with the right stand for your needs.
