Hi Timmo
I replaced mine about 2 years ago by choosing the most gentle route between chassis rail and extractors after leaving firewall. To prevent burning the cable which seems to happen to all, I fitted a zip tie very loosely to hold the Cable via the RH Brake Line in mid air equi-distant between extractors and chassis rail.
No risk to brake line is imposed here as there is insignificant pressure.
I also added a small length of heater hose to Cable to avoid chafing against steering column to box connector.
This is super-glued in position.
Before entering the Bell Housing area, I added a rubber spacer between chassis and Cable to prevent Cable from chafing against Chassis rail.
The above has performed admirably for 2 years with no problems at all.
Start by fitting Cable to Clutch Pedal, then work your way down.
