I can see as a ground up restoration when every item is as new and show quality, but on the other hand, take my car for example. It was totally taken apart in 1973 , every item was off the car. When I purchased the car, it came with the original dash and everything else that was on the car when taken apart. I am not planning on a ground up resto on my car, but want it to show the actual mileage that the car has on it total. My speedo needle shakes, and the trip reset isnt working. I was planning on letting rt specialties rebuild my speedometer , clock, and a tach that MEK sent to me. If they cant do that for me, then maybe they can just give the speedo a good clean and lube job so it works good and retains the actual stuff. I have like 45,950 original miles on the complete body. I got a tune up reciept somewhere here stating that it had a tune up with like 39k on it or so in early 73.
I wouldnt whine and cry if it was set at all zeros again, but would prefer to keep it in actual reading miles if I could.
