well, as far as I know Marlin is working on providing a shift lever with their short throw kits for the W series transmissions, so you could kill two birds with one stone and get a short throw OR try and call them and ask if they sell them separate?
If you live in a state with rust, you can probably find toyotas in junk yards, if you live in arizona then you're SOL cause those trucks are bought before they get off the flatbed.
Good luck!
