Trailer caravan legs and tire clamps

Hello I have four (4) new trailer caravan legs, still in their original cardboard packaging. I bought them for my European caravan, but I sold the caravan and never used them. (I don't know if they fit American caravans or not) Additionally, I also have four (4) tire clamps that I purchased for my caravan. I'm selling the four legs together for 600 SAR. Each clamp is 20 SAR.
