show and tell! Firm Feel sector shaft brace

Hi

I don't want to start a new topic for this so here it goes:

I am far from USA and imported FF sector support would cost me around 280$ shipped... There is no way I am spending this kind of cash on a piece of steel with bearing ;-)
I'd accept the price in USA at 130$ but all import taxes and shipping charges make it less fun for me.
OK done with whining and to the point:

Can any kind owner of this great device give me some measurements that could allow me to fabricate the whole thing from scratch?

Please look at the photo I added and tell me what is the measurement inside the bearing. This is the most important thing for me. I can get such bearing in housing as pictured for 5$ where I live...
Another thing is this extended nut that needs to be installed. Worst case scenario I will tig weld a piece of steel tube on the original nut but the rest is just a piece of cake.
I promise to post photos after job is done :)

Reason for me doing this is that casing of my steering box cracked and I don't want this to happen again.

Thank you for helping me out!
