well Gaz if yours was one year newer, the cheap way is to steal everything off a 71-72-I'm in the middle of doing my second, using spindles etc. off a 71 GMC I knocked in the head a coupla yrs ago.
Its not cheap just cheaper, ya gotta buy new ball joints upper & lower, & replumb & fit a new master, gotta swap for some rebuilt calipers, etc etc
