Hi,
I have a 41 3/4 ton with working doors. I've responded to your email with pictures of the handbrake parts.
Hopefully these are of use, if not let me know what pictures I am missing.
Cheers
This was helpful. It does appear that it is metal to metal contact which would rub the paint. I think the first step is to flatten the new parts to lessen the rubbing. I am also wondering if there was originally some sort of insert that wnet in this area to prevent the metal to metal contact?
