Well I finally made the 3 piece cover fit the taigen hull. It was not easy at all. I had to cut the bolt bar off, its too tall any way because its a henglong part.
I have photos of a 3 piece from a local museum and its much shorter like what I have done here. Wont be a problem to make a new bolt bar.
I made a T brace like the rest of my hack up jobs out of thick styrene and built up the attachment point and strengthened it.
