So I have a 78 f150 4x4 frame that I want to lift. I planed to do that by doing a rear shackle flip, and using the front hanger from a 1970 f250 as the new rear hanger. If I were to take out the lift block, I calculated that it should give me about 4 or 5 inches of lift in the rear. My problem is, I may want to swap superduty dana 60 axles under the frame, and Im thinking about how I would do the front lift. Has anyone done a leaf spring conversion up front with dana 60s? My plan so far was to get more hangers and re-use the rear springs on the 250 up front on the 150 frame (and take out a leaf or so for ride quality.) Feel free to criticize my idea or give me pointers, this is my first build and I have very little idea what im doing.
