I need to do this - I bought some new, had them fitted and they snapped the first time I tried to lift the roof. So, now I have to remove the damaged ones, have the old ones re-gassed and start again. Am not impressed. Am wondering if I should have a go myself having read this?
I put new gas struts on our super viking but found in strong winds that the roof blew down, so came up with these. A plate with a thread in middle screwed to roof and gutter clamp on the other end, plastic conduit tubing to cover threaded bar to neaten things up.
