Mine was in the same condition as Rockfrog's. It was still rolling with the original 1989 radiator...or what was left of it.
I did the conversion in about 4 hours last Saturday with new radiator, overflow bottle, thermostat, rad hoses and heater hoses. I deleted the heater valve. Using all Autozone parts, the total was right at $250, so it's not a super expensive or time consuming project.
