I forgot to tell you, if you have a side glass and working on regulator. do this first to avoid broken glass( I did it and cost me 1000$) took me a year to save up
. anyway I made a template out of cabinet board soaked in bathtub for a day ,then place it over real glass clamp it all round and let it dry for a week. the wood got twisted shape as real glass and you can work till you get the right angle etc. then replace with good part.
