I have a front axle for my 87 4runner build. I was told that it was out of a 1980. I was told that in 80 they didn't have a lower truss, this one does it goes half way . In 81 they went to a truss half way across and in 84 they went all the way across. I am in the process of building the axle and the brakes are the older style that only have the 6 holes. Can I still put the IFS calipers on the older style brakes.
