1961 Cadillac El Dorado

Interior problem
1961 Cadillac El Dorado V8 Two Wheel Drive Automatic 67,000 miles

I have a 1960 Cadillac El Dorado. The speedometer when slowing to a stop does not go to all the way down to 0 it stops @ 30 mph. I notice when I am driving the speedometer reads 30 mph faster then I am driving. This problem just happened over the last weekend. Is there an adjustment to correct this issue?
