Well, some of you know that I just recently picked up an Opel GT and plan to start on the rework next year(after my 70 Challenger TA is completed). So in the spirit of dreaming I was thinking about how the rear interior of the car is pretty useless and was thinking that a hatchback would really help out. I plan on installing a tiny rear seat to accomodate my two tiny kids - and was wondering if anyone had ever made a hatchback. To start with the sheet metal is so thin that it would need a full frame to support the glass. Other than that, hatchback hinges are available in any make and style. I was studyiny my Explorer with the lift glass and it seems that those type of hinges and latch system could work in a GT. Then you would have to address the seals to keep the weather out.
