Hello Toms, the trunk models you are asking about are pretty simple. If you can trace a wood pattern using your trunk area as a reference then you got it. There is a "nailing strip" mounted to the top of wood and then the outer sheet metal is crimped over that. There is a lip that comes up under the fabric roadster top so that water cannot just easily run down into the trunk area. The hard parts to come up with are the correct hinges, deck lid support arms, and latch assembly. The rubber bumpers are simply round holes drilled into the wood in strategic places on the decklid wood framing. A round rubber dowel is inserted to keep the decklid from riding directly onto the outer body. Early 28 roadsters used a tapered square shaft T type key that could be removed after the latch was engaged. A screwdriver could be used to open it but most people do not carry screwdrivers. Recently a 28 roadster was bequeathed to me by our long time friend. It was a VCCA national winner in 1965. From that estate I bought a 29/30 roadster decklid I could take some pictures of. It is very similar to the 28. The 28 roadster is stored over at another members shop for the winter. Art
