This is the one I'm using on my lil banger, I just scored it off Ebay. It all brass and has the Speedo and Tacho combined on the same axis! The right rev range and about the right speed (probably a little low) but man I think its the coolest...........even though it does screw up my pre '35 buiild I think people will understand (if they even notice) What you guys all running/hiding in the sheds...?
