hi . i've got an 87 with the 4L (4x4) and peugot tranny. just wondering what is involved with changing to a different tranny (like one out of a YJ). Also, how hard would it to be to just swap in the complete drive train from a full size blazer (350, SM465, NP208). If the adapters aren't much, that would be an awesome combo. thanks, and long live the comanche!
