Do it yourself. I just rewired the entire front end of a 70 Cuda with M&H harnesses from year one. The harnesses for the entire front end (bulkhead forward) were $350 after 30%off discounts which YO seems to be running non-stop right now. This also inlcuded the "inside dash" AC harness which I haven't done yet. I am thinking about buying the inside dash harness and rear taillight harness just to finish the job. The dash part is more difficult but the engine side was very very simple.
