The fuselage is of fabric-covered steel tube. Aftermarket modifiers have obtained supplemental type certificates (STC) allowing conversion to an aluminum covering. Many different engines have been installed in the 108 by STC such as the Lycoming O-360, Franklin O-350, Continental O-470.

In 1948, however, overproduction in the US general aviation industry led to a glut of light aircraft, with unsold 108s being stored, and on 30 June 1948, Convair shut down the Stinson factory. The name and assets of Stinson (including 200 unsold 108s) were sold to Piper Aircraft on 1 December 1948, with Piper setting up a Stinson division in April 1949 to sell the complete aircraft inherited from Convair, and to assemble a further 125 aircraft from spare parts. These aircraft were marketed as Piper-Stinson 108s. 742 built in 1946.

;108-4

:The 108-4 is a higher powered model 108, sn 108-4693, NX149C, not certified, flown experimentally by Stinson, later by Piper, 1 built. The 108-5 brought total model 108 production to 5,261, of which 5,135 were built by Stinson, 125 by Piper, and 1 by Univair. Jane's all the World's Aircraft 1947, Stinson Operating Manual.
