thread size of Rusty's t-bar

[John D]

I currently have Rusty's t-bar with frame mount and wonder if anybody knows the thread size. I want to make a new
t-bar but want to reuse the threaded end and mount. I need to know the correct size insert to get to go with the tubing.

Thanks

I know this is not what you want but thats the peice that everyone breaks is that threaded insert I would replace that peice as well. I know its weak because it broke on me when it shouldnt have.
