Thanks for getting back.
No sunroof and it is a 2002 Shogun Pining
Do I need special tools? All I can see are small bolts under rail and nothing on the foot.
Must say am pleased with your response.
Thanks to your help I was able to remove the rail and there was no rust at all but I could see some damage to the mastic seam near to the windshield.
I suspect caused by the replacement shield 3 years ago.
However, I applied some mystical all along, put all back and took the car south of the river to find some rain.
A good hour in the rain and no leak.
We are due rain tomorrow (Sunday) and I am confident we are now dry.
Many thanks Rob Venables
As well as going over the mystic I did give all nuts and screws a good covering of grease.
