Have received a pair of handbrake cables, from Luego, but these seem to be a couple of inches too short. Also each cable is fitted with a threaded stud, at the handbrake lever end. In the build manual these appear to be bolted through the bracket on the tunnel, whereas my chassis has a pair of tubes welded to the bracket at the top of the tunnel. If the cables are fitted into these tubes the cable is then way too short.
Has anyone found similar problem or have any suggestions please

Hi mate - you have it positioned properly.

They are ALL too short - major design flaw

You probably should investigate the use of a CLEVIS PIN

Just hook that to the handbrake and then to the cable - should be a couple of inches between them.

Hopefully the new boys will fix these 'STUPID' problems
