Speedometer gears, ratios and woes

I need to get a new speedo gear for my truck for the proper speed reading...the one that was in there was 5 above, then when I acquired the speedometer gear housing for the smaller gears, and after talking at the dealer and trying to match things up, they gave me one that varies from 10-20mph over. Figure that one out...

It has 3.73 gears, 700R4 trans, and P245 R16's. I'm having an annoying time figuring this out, since it's on the backburner of problems I have to deal with before a trip coming up...if all else fails, I'll just pull the thing again and use an old GPS for a odo/speedo.
