I also have a 1930 Buick Marquette 30 series. The noise I am having is when I let off the gas when slowing down. There is a load whining noise. There is a crack in the tail piece of the transmission that I sealed, however I can not find the rear seal for the transmission. I am also in search for the speedometer cable.
Thanks for any help you can give.
