not same year(1980) but same problem. I had to replace my ignition switch and a relay on the driver side kick panel.
my problem happened when I left the positive cable off the starter that I had to change out. My only way to get to the parts store was to pop the clutch with the starter out to get it replaced. I forgot all about the cable....well, on my way home it grounded out and blew the ignition switch and a relay. simple mistake that cost me a weekend of no wheeling trying to figure out what the problem was. I took out my whole dash apart. I had wires all over the place. Two days of fustration...just to have a friend come over pinpoint my problem in a few minutes. The relay looked fine on the outside...but I popped it open to see that it was fried up inside.
post up when you fix the problem.
