plastic/polycarb windows

[hayesey]

the rears are really easy to make to be honest.  All you need to do is use the original glass as a template and cut the plastic to the same shape using a jigsaw, then fit the plastic using the original rubber seals in a similar fashion as to fitting glass ones (using string around the seal).  You don't even have to get the edges dead neat because they are hidden inside the seal.

Just make sure you use proper poly-carbonate material and not something else as other similar materials are more prone to going yellow in the sun and scratching.

Any tips for removing the rear windows ?

start by unhooking the seal in the bottom corner from inside the car and then just work round pushing the window out, it'll just pop out.

If its similar to MK2 Golf's, just get someone to sit inside the car with their feet pressed against the window and get them to push.

Then you stand on the outside holding the window, will pop out really easily.
