will a front set of disc brake from a 67 T Bird with 5 lugs fit a 70 Maverick that came with drumbs 4 lugs all around?
only if the whole spindle fits the hub assembly swaps with later 5 lug drums, but disc swaps require the whole spindle assembly, gotta make sure the tie rods line up, brake lines, bolt patterns, space to mount calipers, etc. Search the parts interchange thread, lots of references there.
