Not sure if anyone makes them specific for Taco's!?! Most any 4x4 reatail shop will have tons to choose from.
Do you wheel a lot? IMO, keep the little bit of wheel travel you have and ditch the stock box for a smaller unit. You can pick up universal washer box at most any autoparts store. I replaced mine with a stock Geo Metro box [$5 at a junk yard] and mounted it on the pass fender skirt near the firewall. Had to chop the long filler neck and find a new way to cap it off but, it works great! If you do go that route, make sure the new box has an internal pump or you will have to run a sep inline one. Anyway, just an idea
