I have a 90 300 Sl , the passenger side hardtop rear is raised, the driver's side is down and is very solid. I would like to remove it, any advice would be appreciated! Thank you!

Am I understanding you correctly that you are trying to remove the hard top and the driver's rear won't release? If that is the case the latch can be manually released if you have the "top wrench" It's difficult to describe the procedure but in the nutshell you open the trunk and reach in near the trunk hinges and grab the release with the wrench and voila. Maybe somone has posted pics before, try a seach.
