speedometer error

I have a 82 ford f150 and do not know the original rear end ratio, but have installed 3.50 ratio gears in it and now my speedometer is showing way to fast. I believe it has a T18 transmission in it. What combination of speedometer gears do I need to correct this situation? I am running 235/15/70 tires. Any help would be greatly appreciated Thanks.
