Speedo cable length for 81 c10 6 cylinder saginaw

[justhorns]

Hey, my speedo cable is going wonky in my 81 C10 4.1L 250 6 cylinder, with saginaw 3 speed tranny. I put a cable in a few years ago and it was 105", and it was too short by a little. Now I look, and the longest is 80". What? cannot find a good listing and LMC doesn't say how long theirs are. Autozone, Oreilly, Napa, non of them help. Anyone know how long and where I can get the proper cable?

I just bought one from O'reillys and it was the right length. Works great and was only like $13. You might give them a try.

Try finding a universal cable that can be cut to length.

Well, I fixed it now. Pulled the inner cable out and lubed it with graphite spray.Put its back in and no more jumping. It doesn't move at all. Harumph. Measured it while it was out, 62". I do not know where I got 105". The cable slides out of one end or the other and nothing. I fix these things all the time in my business, don't know why this has been an ongoing problem since getting this truck. But I will fix it one day.

I fixed it. New cable.. The exact one I pulled out by part number on the cable, but new is 1 " longer and speedo is now working smoothly, for first time since I bought the truck. 3rd or 4th cable. All have been ATP-pioneer brand. New cable fit properly all around. This was the only problem in my truck, that isn't body or rust related, that Ive had for the last 4 years. So, per below, I do not have to sell my tools. Also, used PB Chain and cable lube on inner cable.

Speedo still working great. then driving to Boulder noticed the tach went out. Found the power wire had come out of the fuse box. On that ride I lost my left turn signal (Just the indicator on dash, outside lights work fine). Do I get at the bulb from the back of the dash, or do I have to remove the fascia from the front? I'm afraid if I go back there again, more excitement will happen.

I am only replying so I get to watch this thread, as I have some bulbs to replace on mine and have been meaning to ask this question myself.

Also, glad you were able to fix the speedometer cable

I removed the gauge cluster on my '74 to change the bulbs, but I also replaced the circuit board.

The factory shop manual says you gotta reach up from behind to change bulbs in dash.. I can reach this lower left turn signal indicator, but cannot get it out. Others, I have no idea how to reach them..
