Source for diffuser behind LCD panel

I paid $145 and bought these diffusers with lcd and I totally not recommend anybody to purchase this .. These sheets did not work with precision and I had to order some use broken lcd with frame and brand new lcd and I used sheets from the broken frame and new lcd .. It was way cheaper way $64 lcd and $27 broken lcd with assembly ... Hope this way would work for u as well

Is this the only answer? The place in Texas wants $100 for 3 pieces of differ sheet. That seems a bit high priced. One could by a damaged LCD for around $75 or so on eBay and get the same thing for less. If you have time-the online stores in China sell too.

I might know something but it requires some elbow grease and most likely you won't get these sheets unscathed. These sheets are extremely fragile and even the lightest touch seems to scratch them. Furthermore the top most one (I think it is some kind of fresnel/diffuser sheet) is easily scorched as you mentioned.

What you can do is buy an LCD assembly for a different MacBook (e.g. MacBook 1342) on eBay and remove the black tape at the edge. Carefully lift the LCD and there should be a bunch of sheets behind there. I suppose you could use these as source. You'll need to cut them though which is the reason why I say you will most likely not get it unscathed, but yeah, I believe poorly cut diffuser is better than one that is scorched and doesn't fit well. I'm just trying to figure out how you would want to cut it properly though to minimize the scratches.
