Searching for a template..

Hey there. This might be a bit of a long shot, but does anyone know where I could find a 737-200C template with a gravel kit? I have my own virtual airline on flight sim, and I always like to visualize what future designs will look like. Any help is appreciated.

Many thanks.

DM airplano21, he has a 737-200 template but not sure if it has a gravel kit
