I'm having a bit of a problem with a replacement speedo cable - it is a T5 gearbox from a Sierra Cosworth but is going to an aftermarket speedo (it's in a Fisher Fury kit car), mine is a metal surround like these:

The part I have received is like this:

The OD is pretty much identical to the socket on the speedometer itself and therefore won't fit.

Some digging indicates it may be a standard Sierra cable rather than a Cosworth but I'm not entirely sure? Does anyone know more than me about this?

Thanks
