Shoebox ford c4 speedo cable??

Hey guys I have a 302/c4 conversion in my 1950 shoebox and was wondering how to use a c4 trans speedo cable to my stock speedo in the shoebox??? Adapter of some sort??

 

I used a 65 galaxie speedo cable in my 55 that has a C-4,the cable screwed right on my original speedo.

 

use one of these

I've got a c4 in my 49 shoebox with the original speedometer. I use a 64 Mustang c4 cable. It works perfectly. No adapters needed.

 

no adaptors needed on my '50 either...........

 

IIRC we just hooked up the cable on Legend544's shoebox with no adapters ...
