R129 500SL - hydraulic roof issue

[sinbaddio]

Hi all,

I have a 92 500SL, and the soft top is sporadic to say the least. In fact it now operates by winding manually only. It's been suggested that the seals on the hydraulic rams have perished and the oil has leaked out, rendering them inoperable. Can anyone suggest how big/expensive/complex a job this may be?

Thanks in advance,
Simon.
