[Alaska Jim]

can any of you fellows tell me the size and thread pitch for the end of the speedometer cable that screws onto the back of the speedometer on a 1941 Ford passenger car ? any help would be appreciated. Thank You.-----Jim

The biggest die I have is 5/8x18 and the back of the speedo looks larger and finer than that, if I can figure out another way to measure, I'll get back to you.
This is from a spare '41 dash I have out.

The reason I ask, is I have a '41dash that I am modifying to fit a '29 roadster, and am using a t-5 5sp. trans with the electric speedometer sensor. I am considering using a product called Cable x that converts the electronic signal to a cable drive, but I need to know the type and size of the end of the cable where it screw into the back of the speedometer. the '41 passenger car speedometer I have looks like it may be 3/4 ,but I have no idea what the thread pitch is, and was hoping some one here would know. corvette8n, Thank you for your input. any other help, comments, or suggestions would be appreciated. by the way, the roadster was a pile of rust, passed over by all the restorers and headed to the scrap yard when I found it, and the '41 dash and gauges were the same. I figured building a hot rod out of the stuff is better than seeing the stuff ending up being a new Subaru. Thanks for any help.---- Jim

It appears from the Lokar site that Ford, '48 and earlier, has 3/4-20 male thread (Lokar #SP-1506U)
