I had a leak in the roof hydraulics, after being told that someone could look at it and they would need the car for at least 5 days I decided to look myself, fortunately the good bit was that I found the ram lifting the roof on the drivers side had a leak from the piston, top of the ram was soaked. Replacement found on eBay, all easy, then the hard bit I could see it but to remove was a pig, eventually done and all seems good.
Then decided to fit bonnet lifting rams, bought rams on eBay, in hindsight should have bought slightly thinner, used a pair of L brackets that were heavily modified to attach to hinge plate. Finished job I am quite pleased with.
