Thank you Recee for finding the best suited gear for my set up. Works well good reproduction

Speedo Drive for 727 By BRUCE (posted on 14/04/2023)

Exactly as described. Unfortunately for me I had to find out the hard way this speedo drive does not fit my 1964 727. Quick email back to the guys at HP and the return was arranged and details of the correct drive for my setup was determined and that order is pending.
