Gear vendors electronic speed sensor

I recently bought a used Gear Vendors overdrive but it didn't come with the electronic speed sensor and the short speedo cable extension.
Searching for a speed sensor I came across an electronic one made by Dakota Digital which looks remarkably close to the GV sensor. Even the cable colors (black and white) are the same. I wouldn't be surprised if GV indeed uses the Dakota unit. What do you think?

Furthermore I found a 20" speedo cable with 5/8" and 7/8" ends made by Pioneer which should work. Can anyone confirm that the GV speedometer cable ends are 5/8" and 7/8"?

Thanks
