The Sunny Van I had was a 11/78 Japanese made, round head light, leaf spring A12 powered version. It had side windows, but smaller than the ones in the photos. I don't know if this was factory or aftermarket, as the previous owner had also removed the welded in shelf to fit a rear seat. The good news is the fellow I gave the shell to is restoring it because it's in better condition than his one. I can also remember selling some rims to a father/sun combo, for the sons Sunny Van, which was white with solid sides. Suggested an A15 to the father (I was selling one at the time) but no sale.
