This link will take you to the thread that shows the entire repair process on the Toy Studebaker Collectors Club Forum. http://tscc-online.lefora.com/2011/01/01/restoration-project/ This is the finished model. Cardboard was used to fill in the badly warped roof, and was used to replace missing parts. Elmer's Glue-All and Elmer's Wood Glue were used to bond the cardboard parts to the plastic body and metal chassis! You will get a full understanding of all this when you see the thread, so definitely, click the link.
