Speedometer Cable????

I am having a hell of a time trying to find a replacement speedometer cable for my 78 K20 4 speed. All the parts stores are trying to sell me a 100" intermediate cable but mine is only 50" long and has one male and one female end. Anyone have a source for one of these cables?

Re: Speedometer Cable????

It sounds like your truck has cruise control. Are you specifying that to the parts guy ?

Re: Speedometer Cable????

It my have cruise control cables from the factory but it doesn't have cruise control. In any case, the several parts stores I've visited only show cruise control as an option on an automatic and the ends are different in any case.

Re: Speedometer Cable????

I think I'm not following you exactly.

There are three cables.

1) Non cruise control cable which is very long, probably the 100 inch one
2) Cruise trucks use two cables, a lower and an upper. Both are obviously much shorter than option 1 since there was originally a cruise control transducer mounted on the driver side fenderwell that the lower cable went to and the upper cable came out of.

If the truck originally had cruise and someone has removed the inline transducer, I usually just get the long cable for non cruise trucks and swap the entire thing out with the one piece from bottom all the way to the cluster.

Do you mean like this?



Is it possible your cable is 41", or could a 41" cable work? If so, ask for Pioneer CA3009.

A 61" cable is available under Pioneer CA3005.

Strangely, I could not find a listing for a 50" cable.

Re: Speedometer Cable????

Nope.....Looks like this. I'm thinking that they ran out of 100" cables and just pieced together a cruise control set since there is not transducer, no evidence of one being mounted, not controls in the cab and no mention of cruise control on the option card in the glove box.

You must have a two part cable.

Re: Speedometer Cable????

Two part for sure. Just get the longer onepiece cable to go from speedo to trans.
Even if you decide to add cruise control later on you will need to buy a another new lower cable (male to male) to connect to the transducer.

Re: Speedometer Cable????

That is the lower cable. I went ahead and ordered one from a speedometer shop so hopefully, the problem is solved. Thanks for the input
