Thank you for that,I have the tow bar in bits as it was very rusty,I am rubbing it down and using a wire brush.It was fixed with plain washers and nylon nuts.
Most if not all will need to be replaced as they are in a very bad way.
I have a copy of the instructions, so will work from that,I appreciate offer to do a pic of the assembled tow barbet should be okay.
I will assemble it on the Disco as thats all i can manage, even a bucket of bolts and nuts is heavy.
I will put up a picture when its done, some time to go yet.
