Sorry for the delay, haven't been on this board in a few weeks.  Chassis was built 20 years ago.  It's a Revell ASA chassis with some slight modifications.  The body is scratchbuilt from evergreen sheet.  Wheels and hubs are resin cast items for a guy that did them 20 years ago.  Decals are custom printed from a guy I know on a FB modeling site.  Pretty much all of this stuff is still readily available.  Here is a link to a FB sight where you'll see quite few dirt late models.        https://www.facebook.com/groups/WFCMotorsportsLLC.
