I was trying to remove my SL Hardtop and the rear bullet that connects the hard top to the center rear of the bonnet does not release. I have carefully followed the removal instructions several times and did it in the recommended sequence but when we try to remove the top from the rear it is stuck. Is there an access point. I tried through the truck but could not get there. Help, it is nice weather here in NY and I want to get the top off.
