My take on what a "Classics" Vehicon would look like, yep...using the RTS Jazz mold.
Vehicon ST3V3
Head, and gun are from the RID version. Head is a direct fit, no mods needed for that. I did add a handle to the gun though, so that he could hold it, and look proper doing so.
Gun mount in car mode is a mix match of bits and pieces, mainly LEGO and Megablok.
Wheel covers are made from thin sheet Styrene cut with a gasket maker.
As always, thanks for looking!!
