Done my reading but not been able to find exactly what I am looking for.... I have a 78 FJ40 which is nearing the completion of SOA conversion. Using Stock springs; (reversed and drilled) with a 1.5 inch frame extension with S/R. Also going with the F250 shock towers up front. Not cutting and turning the axle at this point. OK here’s the question..... Those out there that have done this type of lift; have you had success with lengthend stock shafts or have you had to get new ones made...front rear? Thanks for the help!
