Not yet. Still waiting to get them. Pics show a large threaded end so that's probably going to go through a box or cylinder I'll build and screwed down to it. Then it'll be welded or bolted into that rear corner of the frame. The front I'm still working on. I'm also not sure what holes are what yet. I believe these being "double" I need to air up and air down which is not what I want. Might have to find single stage cylinders that retract with a spring. I just need more time out side of work.
