Jesse, Thanks for your patience.

3731911 is a side cover casting number for a 1957, 1958, 1959, 1960, 1961, 1962, 1963 Saginaw three speed manual originally installed in Corvette's.

Please check the number you typed in as 3844857 as the references I have do not show anything with this mass produced number from 1955–1975. Clean it very well and read it again.
