AVION Travel Trailers

Hello,
Does anyone know where I could purchase appropriate camper jacks for a 66 C10 Avion Cabover camper? I recently purchased the truck and camper combo. The camper sits on a flatbed and the previous owner/builder removed the jacks with the intent of leaving it on permanently. I’d like the option of removing it. Any insights on the best jacks to use? Thanks in advance.

Happy camping!

I was perusing old threads and ran across someone who was giving their jacks away, think they said they only had three of them. Probably the guy you bought your camper from.
