This is one of my favorite kits. The body is about as close to accurate as it gets. Puts the chopped Revell to shame to.
If you build another, cut the rear part of the interior out where the hinge goes, glue the hinge to the trunklid. After it dries, cut and insert a piece of round styrene tube in between the hinge pins (they will flex but be careful) Be sure it is snug. Taper the trunklid in position then glue the round tube to the bottom of the body.
There you go, a good working decklid without the PITA, and the decklid can be removed for painting.
