These are the top mounts and found long enough bolts and nuts (home depot) to go through the length of the tent support bracket

Bottom mounts and got the washer and nuts at home depot.
Ours does not go up as smoothly as Habitat. A little pull and push to get it up and down, but relatively easy and no way we would be able to raise without it. A couple of tips, you will need to take off the side panels (attached inside) so as not to rub the piston. Also be careful where you put the bottom bracket. We decide to go straight down from the top bracket and if able to do over, would angle it just slightly inside, since now, the pin for the tent support bracket slightly rubs the piston. Take into consideration the weight you are trying to raise. We have a large tent weighing close to 200lbs. Although the 40lbs struts helped a little, we really needed to go to the 60lbs struts. When attaching them to the bracket It takes a little bit of muscle to compress the strut (especially the 60lbs struts) to pop them on. Funny, with my wife, it took us about 10 minutes to put the first one on and then about 10 seconds each for the other 3, once we figured out the right angle.
I hope that helps.
