Does anybody know if the heater control valve for the 93 FZJ80 will work in the 91? When I pull it up on Toyota Parts online it shows the 91 is NA, but when I pull it for a 93/94 it lists it as fitting the FZJ and the FJ....Same with the lower rear heater pipes that run under the right side and have the curved hoses that attach to the rear heater nipples that come through the floor. Any intelligent would be appreciated. getting ready to attack a bunch of cooling projects and want to address as many old hoses as possible while I have it drained. Cheers!!
