I posted my pictures in another post a short time ago but this is what I did, maybe it will help you some.
Went to the local muffler shop (took my stand) and had extentions made, cost was $ 20.00. They just slip over the original tube and I put a bolt into the hole where the original hook was, this just holds it from turning, it is not all the way thru. At the top I drilled a hole for the hook (the original hook) to go into and attached my carabner to it. I use it in my bedroom so no tarp to deal with.
