After talking with Amaurer. I am going to try and find an electric speedo that will fit into the stock cluster. I can not afford to buy new Speedos and cut them up, but dead Speedos should give me all the info I need and a reasonable cost (shipping). Let me know if you are willing to send me your dead speedos and I wil cover shipping cost. Pm or email me at gulfsurfing@gmail.com.
If someone has already figured this out, please let me know.
