Your control arms ( and possibly your cross member) are from a later truck ( 5 lug hubs and rubber bushes) it could be that the mounts are from the same later truck?? One solution would be to source a pair of original 64 banana brackets ( the ones between the cross member and frame) on this forum then I could give you the part number for the original mounts, I could even source them in the UK for you.
