Removing speedometer cable?

I'm trying to swap guage clusters from my current one with dummy guages to actual guages but I can't get the speedometer cable removed from the cluster to install the new one. Any trick to the removal and reinstallation?

I searched before this post and didn't have any luck.

Re: Removing speedometer cable?

Is it the threaded kind or a push-lock one?

Thirdgens aren't threaded.

Check the first post of the following link for a how-to:

Re: Removing speedometer cable?

I saw that clip yesterday when I was removing the gauges. What I can't tell from the pictures in the post is do I use the screwdriver to pry the clip towards the engine or in towards the gauges. I didn't see this clip on the new set of gauges I have so I'm guessing it's connected to the speedo cable?

Push the clip upward to release the cable from the speedo head. The clip is on the speedo head, not the cable. Hopefully, the replacement cluster is mechanical and not electric.

Re: Removing speedometer cable?

Yeah it's mechanical, I made the mistake of buying an electric first so now I have both. My replacement does not have the clip though for some reason.

Re: Removing speedometer cable?

Interesting dilemma. Without the clip, I'm unsure how the cable can be secured to the speedo head. Let us know how everything works out.

EDIT: I stumbled on pics that may be helpful:
