Yeah, here Valiant Super Bee`s were in production from 1970 to 1980, on 1981-1982 the HP car was an M body called "Dodge Magnum" it is actually quite similar to my Dodge Dart but those had a 360 engine and some other performance enhacements, for instance the Dana 44 axle, similar to A bodies super bees.
BTW e-bay is a good source for hood tachs I think, actually I have been looking for a working replacement tach, mine unfortunately does not work.
