Default Question about speedo worm gear...?

There must be different worm gears for the speedos, correct?

I have had at least 4 different clusters in my truck working with my mods and things, every factory cluster read a different speed. This can only be associated with a specific worm gear for tire size and rear end gears....?

Today I just got my white cluster, put it in and bam! it reads 5mph slow. So what gears were in the sport trac it came out of? 4.10..?

Is it possible to get these worm gears form ford? I need one for 3.73 now that I have changed my gearing.

Anyone got any concrete theories on this? or knowledge?

Its not a a huge deal, but if I sell some modded clusters, I dont know what the speedo is set for...I can set it to the gps say at 55, but up towards 70 it starts to go off, below 30 its off. The only way to correct it would be to get a worm gear matched to the gear ratio. ..................I think...
