Not sure what happened...I replied to your private message on my iphone today and when I went back to read my response from home, both your message and my reply were missing.
I don't know if you got my reply and I don't remember your question...exactly.
The rear glass cost to me with shipping was 609.00. shipping was no problem. I am happy with the fit on my black bodied coupe and the most I think I have to do is perhaps increase the gap size along the sides but I'll let my body guy decide that. The top and bottom seem fine. The glass sits flush with the body along the edges. IF you had to work the body to improve the fit it would be minimal and I think the paint could be touched up to blend nicely. If you had the glass sit 1/8 above the body with a thicker bulb moulding I don't think you would have to do anything to the body.
Tough call on whether to get the glass or not...depends on how much you like the existing hatch. The glass makes the car look that much more "real" and maybe a little less "kit" like. Let me know if you want specific information. Sorry for the delay in responding...I don't check my message box often.
