cable
Hey guys!! I had the same problem a few years back. I just so happened to be working on a caddy at work at the time for a speedo concern. I ended up replacing the speedo cable on the caddy. Now I dont remember for sure the modle or year of caddy , but I belive it was a late 80's Brogham, (you know, the big ol four door tanks), anyway the cable was a two peice, the first half screwed to the speedo gear like any other GM cable on the one end and the other end of the first half cable had an end just like the screw on end of the speedo gear in the tranny for the second half of the cable to screw on to. This first "half" is about 3 to 4 feet long and works perfect as an extension on my original cable. I would think that a GM dealer or junkyard would have this.
