捷克采购需求：货箱盖、皮卡侧踏板、延伸式行李架、货箱升级配件、前后保险杠

I'm interested in your Power Running Boards / Electric Side Steps for the Toyota Hilux and would love to get more details before making a purchase. Could you please share the pricing, availability, and estimated delivery time to the Czech Republic? Also, I need to know the shipping cost. Additionally, is all the necessary mounting hardware and wiring included with the product? Are these steps compatible with a double cab Hilux? I'd also appreciate information on the warranty and whether tracking is provided after shipment. Thanks!
