I have just finished a restoration on 55 chev hardtop, the car will require engineering approval by the Australian road transport board, the only information i have is a dot 516 between the layers of glass, normally if the glass at question is made of 2 pieces of glass it's laminated; although i may have an issue with the road transport department without verification from the manufacture. can you assist with this issue?
thank you
