I replaced my side windows two years ago.  I bought the plexi from a 
local plastics dealer and had them cut rectangular blanks to size.  I 
then sanded the edges with a table sander and fine paper.  I used the 
sander to round the four corners about 1/4 radius and rounded the 
sliding edge as shown on the microfilm plans.  Good directions for 
working with plexi are available in the LP Aeroplastics catalog.  I 
strongly suggest getting their free catalog.  I bought a set of plastic 
ground drill bits and a reamer from them.

I reused the good metal parts and bought some new pieces from Univair 
for the parts that were worn beyond repair (the upper pieces were worn 
to a knife edge and were tearing up the welt).

Make sure to drill the rivet holes oversize.  Also follow the plans 
carefully.  They appear to show the rivets a long way away from the edge 
but that is to keep the track clear.  I used a rivet squeezer and tried 
not to over squeeze.  I made new handles (inside and out) from raw stock 
because the ones I bought from Skyport were pretty bad (they would work 
but the workmanship was rotten).  The FAR's allow you to do the side 
windows yourself (and make the parts also if you are the owner) if you 
sign the work off properly.

I also replaced my rear windows from raw stock.  I cut them with a $119 
home depot band saw.  The band saw cut the material to basic shape based 
on the old windows I removed then I sanded to final shape.
