Can anyone help me to find a speedo gear for my 2wd getrag I replaced the gear on the inside on the main shaft and I have a new sending unit but I can't find the gear for the sending unit. I have 3.54 ratio in the rear end I don't know what that translates to in tooth count but any help is greatly appreciated.

 

Do you have an old gear with a number on it?
These gears are the same design as the NV4500 through 1997 and pre-'91 automatics in a lot of Dodge applications.

Mark.
