I took the hard top off and tried to raise the conv top.It does come up,latch at the front,the rear cover(near the trunk) raises--------but the rear of the conv top willl not go down.Of course-I have not forced anything-yet.Any thoughts before going to the dealer-Thanks,Fred

I can't help you with the top but would you please post photos of the 50.0 liter engine?
