Quoted from BoP:My cabs looks sensational with the Next Gen decals applied but like you the playfield and plastics could be better. I just came across these replacement clear plastics also. http://www.bestofpinball.de/catalog/product_info.php/products_id/13927
Not sure if there available else where also but I had some other parts ready to ship already and added these to. I'm just looking forward to replacing the large yellow plastic which sits over the helmet with a nice clear one.
Wow, nice find. I ordered these as well since I haven't seen them anywhere and mine are so gross and yellow.
