From what I find in the 1929-1957 Parts manual, you have two options (highlighted on the attached.) A good parts store can either use the dimensions and the GM PN to cross over to a current manufacturer's number.
NAPA's website says their Part #: NOS 22340 fits. It matches the dimensions in the first seal I highlighted.
