How to replace fuel cap emerg cable?

[clickman]

I managed to bust off the little plastic emergency cable for the fuel filler door release that you access from the front of the passenger door.

(Did I say it was little? It's like no thicker than a human hair! Come on Porsche! )

Anyhow, the free version of the workshop manual I found on the net doesn't make any sense (as usual). It talks about accessing it as part of removing the fender .

I took off the wheelwell liner, and it looks impossible to get at from there.

Has anyone out there replaced this 10c part?
