My cabrio came with a hard top. In about 3.5 years of owning it, I had only put it on once until this last weekend. I can't figure out how to get the pins in the back properly adjusted. I have the special wrench that is like a hooked crescent at the end, for the widest component of the pin assembly. However, that part doesn't want to move much at all (on either pin). There's a lock-washer type part beneath it that seems pretty well locked up. Also, up above that part of the pin assembly are what appears to be two independent bolts stacked on top of eachother. How are those related to the adjustment procedure? Currently, the hard top is on the car with the pins in the sockets and the front latched down normally. I can drive around with it like that, but I want to be able to have it fully seated in the rear sockets, and know that it's correctly mounted. Thanks for any help.
