Check carefully on what strengthening has been done....And the quality of it.
Assuming the perpetrator of the crime actually bothered with any reinforcing.
i once looked at a late 260Z here in England that had a pair of targa roofs of Italian origin put in it.
The only strengthening was one bit of ally plate pop riveted between the two panels on the roof.
It gave a whole new meaning to the phrase" Unsafe at Speed".
I walked away from that one .... fast:icon45:
