Well the 67 frame in the states didnt have a spot for a power steering box where the 68 and newer did. Also, from the picture in your avator, you may have a RH drive truck which may change things.... but putting that aside, the 73+ crossmembers will bolt in using two existing holes and then you drill two new holes. There are some tie rod changes and your control arms may not fit the 73+ crossmember... I would check with LMC or ECE about the interchange of their respective parts....
