Someone posted that they believed the printed circuit gauges started about 62 or 63. I cant say for later years, but I know for a fact after disassembling enough of them, that the 62 and 63 still used separate gauges for the instrument panel and had no printed circuit. I think that 64 may have been when that started, at least for the lighting and warning lamps. I had a 64 instrument panel that still had individual instruments for the gauges, but had a printed circuit for the remainder of the panel circuits. Lets hear from others who have been behind the panels of later years and who may know for sure on them. Mikey 62 Crown Coupe
