The 63 had the red three on the tree column the 64 has the black one which will be going into the 63. The connectors on the wiring harness are different. My thought was to just cut them about 4 inches back and splice the wires together. They are the same color wires on both columns. The thing I noticed was that the 64 was an automatic car with power steering and it is shorter than the 63 calm, I don’t think that’ll make any difference since I put the power steering in the 63 thanks…
