Just got this jeep a couple months ago for my 17th birthday and have been working on it since so im not by any way a jeep expert. while changing the carb to a weber i disconnected the 4x4 vacuum ball thinging and threw it away and now the 4wd doesnt work.. so i bought another one off line but im not 100% sure which vcuum lines go to it. if anyone know please help. if u have pictures that would help... Thanks!
