The Lotus Grand Tourers

Found that the speedo cable has come off the back of the speedo. Have removed the instrument panel but find that the cable is a little short and I cannot get my hands behind the panel to screw the cable on. Pulled the cable as far forward as I can and tried to get at it from beneath without success.
Does anyone have some suggestions.

If you have access to where it attaches to the gearbox then I'd suggest undo that end, reattach to the speedo head then reattach to the gearbox.

Thanks Andy. Will give it a go.

I found that by disconnecting the cable from the clip just in front of the bulkhead (in engine bay), that gave me a bit more travel and the instrument panel came forward enough to get my hands behind and unscrew/screw the cable

Thanks Rob much appreciated
