Hi Stuart
The shaft you cannot see, is this the one with a lug welded on with one hole, when I turned this it activated the two outer cables, hopefully this is the one and is still present. If this is the case, can I buy anywhere the missing parts.
Yes, that's the one. So you should only need the rod and clevis joints which connects the E-brake cross shaft lever to the main cross shaft.
There is a parts for sale forum on here, I have had components posted to the UK by one of the stovebolt guys on here.
Alternatively, you could get this part made up by someone in the UK; it isn't a complex component.
Stuart.
