Did all Avanti bodies come pre-drilled for an antenna or was that done on the assembly line? It would seem there would be a fair amount of variation where the antenna hole was located if done on the assembly line assuming there was no locating device where to center the hole. Then again...Molded Fiberglass was contracted to supply complete, painted bodies to Studebaker...were they expected to pre-drill the antenna hole? I guess that would incur an extra expense paid to MFG when Studebaker had their own people to drill holes.
