Solicitudes De Automotriz - Vehículos / Carrocería - Piezas Del Chasis

I am looking to buy cargo boxes and boxes that can be used as functional unit on top of our electrical three-wheelers

we are interested in shelves for Light Commercial Vehicle interiors, e.g. workshop fittings such as sold by companies such as Sortimo, Bott, etc. Can you recommend any company of this kind?
