DWG32BB,
Some pictures of your project would be great!
I am fortunate my cable is still functioning to some extent. I had to make some modifications to the wire portion but wanted to still have the original knob in the cab. I finally had to remove the outer sheath and just use the wire to "pull". Then I had to add a stiff return spring (not original) to move the wire back to the home position.
All that may or may not help you. Good to know that there is a source for a reproduction B type starter cable too.
Regards,
Chris and Cheryl
