I am in the process of changing over my ignition on the rally car to a MSD arrangment. I would like to avoid having to use 2x tach adapter modules that MSD sells. Apparently it is possible to have the guts of my original 1970 tach modified to accept the MSD signal?? Anyone had this done at Palo Speedo or Hollywood??

Thanks for the info, launch is 2 weeks and counting to fire the 'ole girl up.
