Thanks, I've done a quick fix with a 2" gap, its a right faff. I had to cut the tubes off to the get old cable out then weld them back together, cut the swaged ends open and for now I've put the new cable in and put rope clamps on the swaged parts to clamp the new cable. That's why I can change it later. The clamps I used turned out to be poor quality (DIY grade) so I'll have to re-do it anyway. I got a rough measure off the section drawing in the manual but it doesn't say whether its loaded or unloaded.
