A good friend of my father’s has a modified Roadrunner with a 440. For performance and improved gas mileage he has a Richmond six speed (ROD). He has had it for awhile but it is failing and needs a rebuild. He has contacted them but they do not respond and none of big parts suppliers sell the ROD anymore.
Knowing that the people on this site have extensive knowledge and American Muscle in not my strength I was hoping someone here may have suggestions regarding options to have the transmission rebuilt or other available transmissions to keep this ride tearing up the street.
