Hi, I have bought a new pair of door locks from Superformance because the key that I have doesn't appear to fit my locks. However, I can't for the life of me work out how they attach to the rods at the back. The parts diagrams show a small plastic bush in the end of the rod, with a C-clip to hold it on. However, my "original" locks have a thread spindle at the back with a nut, but the new locks have a brass ball-end spindle that doesn't even fit through the bush. I have raised this with Superformance and they are completely baffled as well. Can anyone help shed any light on how it is supposed to go together? I was assuming that my locks had had the threaded spindle added at a later date as a fix, but maybe not. Paul
