English Axle Handbrake Rod Bush

Hi all,
 
I've got MKII Escort with an English axle that appears to be missing a bush in the center of the diff where the handbrake rod sits, so the rod just floats around in the metal loop.  It doesn't affect the operation of the handbrake without it, but all the same does any one know whether replacements are available, and from whom?  I've no clue what the thing is even supposed to look like.
 
Thanks!

Thanks Matt, that's a big help.  Now to find something like it!

You'll like this one, was redoing the front suspension and noticed the same problem on my axle. Looked around on the floor and jammed the old inner tca rubbers In the hole they fit perfectly!
