Hey im new to mud but i've been lurking around for awhile. anyway i have a 78 fj40 that im restoring its a rolling chassie now with just the engine tranny an t-case on it. i've done a soa conversion as well as a shackel reversal. i want rancho 9000s but i dont know what length i need. the measurments are 24" from mount to mount in the front; 19 1/4" in the back with the vehicle lifted off the ground....22" from mount to mount in the front 18 1/4" in the back with the vehicle sitting on the ground.......thanks
