Alright people! It's true! Leaking hydraulic roof actuators CAN BE REPAIRED! All you people in this group rock! With the advice from the threads herein, Marty Ewer and a few others in the group and a dozen or so hand tools I managed to rebuild the two actuators that raise and lower the roof. Sucker works better than when I bought the car (which may explain why I got such a good deal on it). All told the whole deal, including buying a few extra hand tools and the long difficult search for M15x4.5 (!!!) o-rings, cost me no more than $75.00! Beats paying 350.00 plus per actuator or even Thousands to a dealership! This was all done with the actuators still in the car. Thanks again to all for your help and support! You know who you are! I hope to post the procedure with photos in the near future. See you all on the road!!
