Technical Speedo cable length

What speedo cable length have you used on a ‘32 Ford roadster to a Chevy (Muncie) tranny with the connection on the passenger side. Thanks

 

@e1956v , have you got an educated guess on a length?

 

I'd probably do the "two coat hanger trick".
Mostly straighten the coat hangers. Route one from the fitting on the back of the speedo to where you want to pass through the firewall or floorboard. Then route the other coat hanger up from the speedo fitting on the trans to where you plan to pass through the firewall/floorboard and mark or cut off any overlap. Measure the total length.
Plan for gentle curves and a couple of clips to hold and hide the cable as well as possible.
You got this. I'm betting you can do it the first time, most of the time.

 

On special order it’s always better to figure out your routing and measure. In the long run it saves time and money.

 

I don’t have the body on yet so no educated guess. Hoping to hear what others have used

 

I used a piece of vacuum hose to mock up the cable. Call Rusty and get it done. https://www.speedoservice.com/

 

I can tell what’s probably too short.
Had a 48” one on my 5W with a Saginaw 4 speed, but after I updated the car to steel floors and a TKO, I needed a much longer one (completely different routing that I liked more). The original 48” one was already a smidge shorter than I would have liked as it was too visible when I was seated in car.
Just about to do a cable for my current 32 roadster project. Have the floor/firewall/dash routing figured out but cannot remember for sure what length cable I bought (pretty sure it was 63”). BUT, I also bought a couple of the fittings so I can shorten if need be.
Suggest following above advice if you are not comfortable following a similar path and probably needing to shorten one.
Make sure you know where you are putting speedo and what routing you want first.
*** NOTE: You can buy pre-made cables for $10-$20 from summit, so if you mess up, take comfort in the fact you will probably make some much more expensive booboos when building a pre-war hot rod. I know I have. .

 

You bet!! Couple more weeks and I’ll get mine up and running

 

Probably too soon to start thinking about speedometer cable length. I'd at least want the body on the chassis to get an estimate of routing and final length.
