Unhappy Speedo gear needs to be changed,help?

I have a 90, F250, 460CI with a newly installed 4:10 rr axle assy. My E4OD needs to have the speedo gear changed to record actual speeds. The rr diff. was a 3:55. My tires are 235/85 16. Anybody have any idea on what speedo gear I need? I checked my speed with a GPS. Truck speedo read 60mph while GPS stated 52 mph. Then I sped up to GPS reading 60 mph while the truck was actually recording 68 mph. The speedo is reading 8 mph too fast. Anybody know which gear to buy from Ford? Thanks in Advance and Merry Christmas.

By the way, I called the local Ford dealer, (parts dept.) The rep. said he has no selection guide for what gear is needed. Go figure????? He did add that all he knows is that the gear color is important.

Does your '90 truck have a mechanical speedo, cable and gear setup? My '92 has an electronic speedo that reads off a speed sensor in the rear axle, no speedo gear in it. If your speedo has the digital odometer in it, it should be electronic like mine. I thought they started with the electronic ones around '89??

Mechanical gear and cable setup

I stopped by the Ford dealer today and got a 20 tooth gear which I was told should work. I'll try it tonight and post my findings. Thanks for the reply.
