1964 CP77 speedo conversion

I have a 1964 Superhawk with a type 1 (apposing sweep) speedo needing to be replaced. Ebay produced beautiful type 2 (same way sweep) for me. Has anyone made the conversion? What will I need?

Thanks!

to my limited understanding, they just mount slightly differently.
the previous owner of mine put a type 1 on the bike that should have had a type 2. i had to drill little holes on the side of the type 1 to get the screws on the side to take to it properly.

Thanks for the speedy reply Gun. In my haste to post, I may have left out an important item I discovered. I feel like the rotation is opposite between the two types. I can only get the Type 2 to register a speed when I push the bike backward down my street. Which has amused my neighbors a little too much. It looks to me to follow the rotation of the needle. CW for type 1 and CCW for type 2.

Any help is really appreciated.

How does one tell the difference between the drives? Thanks,

By attaching it to the wheel, spinning the wheel, and observing which way it turns.
