Thanks for your thoughts on the sunroof, I tend to agree that it may well be the lift slides which are binding....I doubt they have rusted/rotted as the car was kept in a dry barn for approx 18 years, but the lubricants etc have most likely dried out in the worm gear and other moving parts. Definitely not sealed up.....it'll move about an eighth of an inch and then its rock solid !
Just wondering if I sacrifice the inner headlining of the sunroof, if that'll make the working gear and drives accessible ? At some later stage maybe able to source a replacement for the lost lining ?
I had asked the previous owner if the sunroof worked and he did say it tilted and that was all. Haynes manual say if the roof can be tilted, then the inner roof lining is removable, but if the roof won't even tilt ( back to the lift slides! ) then for the moment I think its fu**ed !!!
