Hi I’m from South Australia I have an 1961 s series that needs tlc

S series valiant is like a 1961 or 62 Plymouth the gearbox is a no sincro 3 speed manual the motor is around 1969 to 1970 I have the right fly wheel I don’t know if there’s any other differences cheers
Ok that sounds like the A903 3 speed. Does it have a flat plate on top?
