Hi all, I am new to the vintage caddy hobby. I have a nice 74 Eldorado but the trunk keeps popping open going down the highway. I have narrowed it down to the mechanism that pulls the trunk close. Occasionally when pulling the trunk closed it will slip and pop back up also. It seems to be a complicated system which requires timing of cams and trip levers and who knows what else. Has anyone experienced something like this before ? I purchased a car last fall and have put on about 400 miles on it. Only in the last 200 miles has this started to happen.
