Speedometer match between 1939 speedo and 700R trans

Posted by boosquat On 2016/1/9 21:29:26

I have a 1939 Super Eight sedan that I have upgraded to a crate motor and 700R automatic. I have the original 1939 speedometer I have had rebuilt and would like to keep. Has anyone any advice on mating the 700R to the stock Packard speedometer? Will the Lokar speedometer cable work? The original speedometer was made by Stewart Warner, so the threads on the fitting on the back of the speedo should be some type of standard size.

Any help or advice would be greatly appreciated.
