Speedometer gear

I'm trying to find out what speedometer gear needs to be put in my truck for 35inch tires. It's in the transfer case.

you can try and calculate it out, but i have found the best thing to do is buy the assortment pack and just try different ones. you most likely will NOT find one that is dead on. it might be perfect up to 35-40 mph then read slower from there up, or the oppsite.

Where would the best place to get an assortment pack?
