I have the WHITE sender for the 700r4. This is the one you will need to be able to use the 40 + tooth gears to get your speedometer to read correctly after some gear swaps.

With 3:73's and a 26" tall tires I had to use one of these senders,a 43 tooth gear($14 at the dealer) and a 15 tooth drive gear which was stock in the transmission.

I will take $50 shipped in the U.S. for it.

Consider it sold. PM sent.
