having trouble. My uncle started this project and spent a lot of time and research and its not all working out. Changed out the ball joints to new stock ones. The disk came from a later model (75-78 I belive) hilux. Some sites say that it is a direct swap and others say that the lower ball joint need to match the year of the disc. Well the stock one is too small(wiggles in the lower mounting hole) and the ball joint that match the year of the disk works in the mounting hole of the disk but the three bolts that go up into the control arm are off by just a little. Do I have to change out the lower control arm? Or is it possible that the disks are not from what they said they were from? Help?
