Am I doing something wrong or do I need a different tach with the MSD box. 1970 Barracuda Convertible 1968 Satellite Street Strip car 1654.5 Mustang 1955 Land Rover

MSD still manufactures 3 or 5 differnt tach adaptors that I'm aware of, but not sure which one you need.....they usually range from $35-$60 depending on which model Rickster

I believe the one he needs for that tach is MSD's 8910 Adaptor, they run about $35 Rickster
