Manual Locking Hubs

Hello Everyone,
I just purchased a '99 Toyota Tacoma TRD and was wondering if there is a kit out there in the aftermarket world to convert the automatic locking hubs to manual locking hubs? Or would it be better to find a wrecked Toyota with factory manual locking hubs and get those?
Thanks,

If you go to OffRoadSolutions.com they sell a kit that includes everything for the conversion to Warn locking hubs. It is quite pricey though about $900 just for the kit not including labor. It is cheaper to dig up all the parts from a wrecking yard and a Taco with manual hubs if you know what all to look for. You will still need someone to do the conversion because it requires a very powerful press for a couple things. I found out a lot on Marlincrawler.com forum.
