[ratbox]

what are available rear ratio's for a 1969 l-78 4 speed nova? is it possible to have a 3.42 non posi from factory? . that's my ratio with correct date to car. and car is a proper l-78 4-spd car. with non orig trans. but with that rear i would assume it was a m-20 trans car..ps anyone have a correct distributor for me. that's reasonable? i believe 1111499 and also 4346 holley. anything before 3rd week feb 69.thx
