'69 TH-350 speedometer cable length

Hello guys,

I want to put a speedometer cable on my '69 Chevelle Malibu and went to Autozone to get one but they want way more info than I can give them. The car is auto of course, th350, column shift, no cruise control, has the push-in at the gauge and screw-in at the trans and that should be more than enough info but NNNOOOO!!! They want to know how long it is. I don't have one to measure.

My choices are:


Anyone know which of these is right?

Thanks Ray

Does anyone know where I could find this info. I've searched here and googled. I guess if worst comes, I could take a piece of string and get a close measurement.

Not much help here but if I were you I would go to a local speedometer shop and get a good one.

Re: '69 TH-350 speedometer cable length

This is a very late response to this post, but maybe someone will find it useful. Seems there is nothing definitive out there.

My '69 Malibu has a 350 / TH400. The speedometer needle would fluctuate ±5 mph, and I found the speedometer cable was laying on the exhaust and the casing had burned through. The old cable measured ~58" and was routed from the transmission, over the exhaust, on top of the driver side frame rail, back toward the middle and up through the firewall. The 3rd party stores had various lengths, but nothing close to 58". I tried the GM dealer. Nothing. Autozone had a 47" that I thought would allow me to keep the cable away from the exhaust, but it was about 3" too short. The 61" (CA-3005)worked fine. I routed it a little shorter under the car, added a loop bracket to the frame (existing hole) and took up the slack with routing behind the dash. My understanding is the manual missions have the cable out the passenger side and need the longer cable as a result. Maybe the 120". Installation is easy. Speedometer needle no longer fluctuates.
