I removed all bondo and I think the roof is salvable.
I dicided I don't gonna chop the front windchield. Instead I will raise the upper window-line and insert the original glass again into the new opening. I also shortened the roof 2cm's (aprox. 3/4 inch) so the front posts will slant a bit backwards.
I chopped the top an inch and a half
I lowered the back window a bit more just for looks.
The front posts where crap, i'll have to re-do them again together with the complete front half
of the roof witch is covered in 10 pounds of filler!
