I just purchased 8 Dorman inner cable kits on Amazon for $3.45 with zero shipping and no sales tax:
If anyone wants one, let me know. They don't have an expiration date, so I don't mind keeping them on the shelf for a while.
All you really need from the Dorman kit is the crimp on end (you could reuse the inner cable that comes with outer sheath you cut shorter). Dorman supplies a pretty nice cable, however -- you might want to use it instead. I used one on one of my church's school buses to make a replacement oil level dipstick (filler tube makes two wicked bends on the way to the oil pan -- cable snakes through perfectly).
I have no idea how to use the little crimp tool that comes with the kit, and have doubts how well it would work anyway. I crimp the ends on with my electrical staking tool.
