Perspex windows use sliders (if you want them) not designed to go up and down Gus.

They would scratch like **** and then look siht (SP ? )

Rear windows can either fit into original rubbers or just be drilled and screwed to the window lip (normally under the rubber).

Will save masses of weight, but you loose security and will probabbly leak if kept outside.
