Help with Emergency / Parking Brake Cable

[mdepot]

I have a 69 3/4 ton std 4wd 127" WB that I need to replace the front parking brake cable on. I've been looking for a replacement part but have not been able to find one. I have found replacements for 2WD trucks, and for 1/2 ton trucks, such as the one here:

Does anyone know where I might be able to find the right cable for my paticular truck?

Assuming I can't find the correct one, I think I might have to make due with the 1/2 ton cable and perhaps modify it, (or the mounting points, etc.) so next question is does anyone know just what the difference is between the cable I found above and the stock cable on my truck?

(No I havn't pulled out the old one yet. Waiting for a warm enough winter day in New England. It might be while... )

Thanks!
