What is needed to put a J10 T18 into a '76 CJ5 with a AMC 304?? I will be replacing a T150 and Dana 20. The outfit I located has a Dana 20 also. I am planning on buying new driveshafts, but will the rear one be short enough or does it need to be a CV one? Don't yell at me yet-I did research this site and have taken notes for almost a year on this. I just can't sort all of the info out. Please list the adapters, driveshafts and lengths if possible, new clutch disk, etc. I am trying to decide if it is worth it. I do off road but not radically yet-the Jeep will be mostly new when this is done.
