imitation fleetside

very limited production - Cameo-specific parts unobtanium or very spendy, but I think you'll find a few in the gallery

Not really imitation. They came before the Fleetsides. To another poster, real Fleetsides started in 1958, not 59.
The El Camino came out about the same time. So Cameos went away and you could choose between the two new models to replace them.
