No less than five speedometers were used in Chevrolet trucks during the Advance Design years, 1947-1955. If you want your truck just right, be sure you understand the differences. Restoring one you have on a shelf or purchased at a swap meet may not be proper for your year. The following will provide a description of differences.
1947
Red-Orange needle. Lower two tabs 4 3/4″ apart. 80 MPH (A clear needle means the color has faded away.)
1948
Red-Orange needle. Lower two tabs 6″ apart. 80 MPH
1949-1951
White needle, lower two tabs 6″ apart. 80 MPH
1952-1953
White needle, lower two tabs 6″ apart. 90 MPH
1954-1955
Totally different from earlier years. Silver needle over black face. Few parts interchange
Then there is the GMC speedometers used during 1947-1955 (Only 1952-1953 are the same.) That is another story!
