I have the threaded rod if you'd like me to send you an adequate length. You'd have to cut it in half yourself but I did it with a hacksaw and it worked perfectly. In fact my cut wasn't straight at all and it still worked. What length do you need?
Yes it is something like that. The bolts that come with it are 50mm so 65/70mm would be about right. I can't remember exactly but I had to buy it in 18" length.
