Speedo cable questions 64 Savoy

Will a speedo cable from a later B body 66-68 fit a 64 speedo head unit. Since I'm converting my car to more street than strip I was thinking of a working speedometer. My factory speedo cable used a one piece adapter that is part of the cable.
Any one else use a later B cable in an early B body

Are you going to a later trans? If so there is a cable made for a Camero that works perfectly, I'll have to look throught my notebooks for the listing and will get back to you.
Also a 66 cable works too.

Gus when my son put the new TF in his 62 300.He got a cable from Imperial Services.Steve used the new end for trans and the small end for the speddo.Early trans didnt have the thread type speedo at trans.Rocky

Contact Redline gauges in Southern California..... They can probably build you whatever you want, and a quality made cable/housing.....

Just A bodies here but the problem I ran into with a 64 A speedo and a later trans was that there was a one year only cable that matched both ends (66 or 67?). not sure if that helps or not. I might still have it if needed

HeartbearCamero.com
Google Heartbeat City
$38 ,different lengths too

Later trans? I used a '66 Charger cable from Imperial Specialties in my '63 & '64 stock speedometers, worked fine with later 727 & 833 I'd installed in them.

Thanks a lot guys this gives me all the info I need to get my speedo working. I have been using late model transmissions since I pulled the slant and three speed out. I never used a speedo with the Richmond 5-speed because it used a GM style adapter. Now I have a street Hemi box in the car and it would be nice to know how fast I'm going

Thanks again guys

I put a 73ish 727 in my 64 Belvedere wagon, and bought a speedometer cable kit at CARQUEST. They had a housing with the proper ends, and length close enough. I had to make one end of the cable itself with an end that crimped on after I cut the cable to proper length to fit the housing. It wasn't expensive, and worked great. I don't know if they still have something like that since CARQUEST is now Advance Auto Parts. Good luck.

You may want to do a search on Imperial Services before ordering anything there. Plus, I think any number of the suggestions here using off-the-shelf parts store stuff could work. It depends on what transmission you have.

Check Control Cables, Inc. in Santa Fe Springs, CA. http://www.controlcables.com/

Chances are very high that whoever is selling cables is getting them made at this place and $$$ marking them up. Send them either dimensions, two cable housings each with the correct end fittings you want to use, overall length measurement, etc. They are VERY helpful over the phone or internet and they catalog your application if you or a buddy ever needed another one. I've had them make stock looking throttle cables and E-brake cables for early B-body using Wilwood disc rear. I've been extremely satisfied with their work. Short turn around times but always good to have your 'end in view' and work the long-lead time parts of your project first. And, Redline Gage Works in Santa Clarita, CA are simply awesome at what they do. And, no. I don't work for Control Cables, Inc.

Getting the proper tranny gear so the speedometer will read correctly may be the hardest part of getting it working properly
I'm getting ready to go through that now on my 1966 Dodge Coronet Deluxe that was a six cylinder three speed car originally that now has 464 C.I 440 pump gas motor with a Dana 60 with 3:54 gears and a NP 833 O.D. tranny Thankfully I have a decent selection of OEM gears with different teeth count on them so maybe I'll get lucky and have the correct one to get it to read + - 2 MPH at 60 MPH

Cab try finding the correct gear for say my 65 with 3.91s.let alone when it had 4.88s.Rocky

You may need the gear reducer, I don't know the proper name for that device, like the factory put on the original M.W and Hemi race cars that came with 4:56 or lower gear sets on the tranny to hook the speedometer cable to

Yeah I know Imperial had them.If I can ever get ahold of Steve Ill ask about one.Im going 4.30s when the Dana goes in.Rocky

Now all I have to do is find someone to loan me a cable to try and if it fits I will know what cable would work for my combo Good thing I live close to so many Moparts guys with large parts stashes
Thanks all who replied

Gus

The reduction unit is only .80 so it barely covers 3.91 with most tires; 4.56, nope.

My 1963 415 HP Belevedere with the 4.56 in it had that on the stock pushbutton tranny, I bought that car from the second owner in 1971 and it seemed like the speedometer was correct according to the CA speedometer checks on the freeways back then with the F70x14 Firestone wide ovals tires on it

Like I said the GM cable fits both ends, screw on end for cluster and screw on end for trans, in any length you need, for $38. There are more than enough speedo gears for the 66 and up trans to choose from to get the speedometer right.

John I run a 3.23 gear now as thats what came in my 65.The speedo is appx 20% fast so i know how fast im going.Now when I had the 88s in it I could hit over 100 realfast speedo.If I ever get the later 4 speed done ill be able to use a lter gear.Rocky

The math doesn't work. With a 26" tire and the largest speedo pinion you'd need a .74 reduction to be correct. The odometer is a better indicator of correct speedo pinion.

I don't remember what the gear tooth count was on that gear but doing the time and distance test on the speed and distance came out around 1 to 2.3 % slow per mile back then at 60 MPH indicated

I posted about this a couple years ago. Here it is.

I could not find this info on Moparts or anywhere else and had to figure this one out myself. If you happen to need a retrofit speedometer cable for an early 1962-1965 B-Body using 1966 and later 727 Torqueflite, I found a perfect part that fits. Hold on to your chairs, it is for a '67-'68 CAMARO!!!

The original speedometer cable for my 1964 Plymouth Savoy with the pushbutton 727 measures 68 1/2 inches. I found that the 1967-68 Camaro originally uses a 69 inch Speedometer Cable Assembly. I ordered one on eBay, and installed it yesterday. It fits perfect and fits the 727 and speedometer like a glove. FYI...I tried the local Napa, Autozone, Oreilly's, ect, for a 1966 Plymouth Belvedere, and all were way too long (like 14 inches too long) not even close to the right length, so back to the internet for parts. This will save you some time, try these links:

Part numbers on the speedometer cable is SC-72 and W-871.

This is what I used for my '63 with a later model 727.

Fit and worked perfectly!

I used a 66 cable in my 65 Coronet 440 with a 68 4-speed worked and fit perfect - I got the cable at summit - I know Brewer has them also

This is good info. I use a 1970 trans in my 63 and dont have the speedo hooked up. I go by the tach to have an idea about how fast I am going but if that Camaro cable fits as easy as you guys say I may get one to try in my 63. Thanks for the info guys as I appreciate it. Ron
