Okay gents - I'm getting a little bit lost here. However, I've got some photos now so perhaps you can distill the information you've shared into 'Idiot Speak' so my addled brain will understand. Here we go...
Here it is in all its rusted surface glory.
Here's another but more of a long-shot along the leading edge
Here's the trailing edge.
Okay, so this is where I'm losing it. This is my sunroof closed.
Opening just a tad - the 'lining' goes with it.
Sliding back, the lining is still 'in the sunroof'
Fully open, here's the horrible part.
So I'm sorry guys but I don't get it. you are absolutely right, in this sun I cannot have a glass sunroof without a blind but I'm thinking my current headlining is the blind. Have I got this completely ass-backwards? I thought if I replaced the metal with the glass it'd just slip into place and my current headlining would remain in place.
I'm so bloody sorry for my stupidity but if anyone has the patience to walk me through this step by step then I would be so deeply grateful.
Thank you, Simon.
