Just thought you ought to know or atleast check your back window on a cab. sit in the back and have a good look around the black metal frame for any sign of rust no matter how small, with your fingers flip back inch by inch the rubber around the frame inside checking underneath for any moisture or rust. If there is nothing there your fine
If there is you will need a new window frame, I had the roof changed 6 month ago and saw the state of the frame the inner lip in one corner is gone completely only initally noticed by the rust damp mark on the parcel shelf. Ive patched the old one up but its beyond fixing.
have a look as it is costly to obtain one off the shelf and 2nd hand is rare as people will try and sell you the whole roof
