@bunch, cost of just glass for JLR I was quoted $2300 with my discount.
@JonnyO, yea I'm 100% if it's leaking at the moment, I just did it, but I did a good job, so my guess is it'll leak or at least water will get in, freeze then really crack in the winter. I may try to Resin it myself and try to seal. I took it to glassmasters today, they said it's about 6-8hrs labour plus glass, so about 3500ish if I get the glass from JLR myself. But I'll try to resin and seal it myself first.
Another option is I have friends at a Fab shop, I may see if they can make me a tin roof panel and seal it up permanently
