If me, I would hard solder a piece of same thickness (with more height than required) stock onto top of trigger bar, then file to correct height. [/quote]I did something similar to my CVA Kentucky pistol , with JB weld . I built it up about 1/4" higher with the JB weld and then filed it down until it worked correctly . I've shot it over 100 times since then , and it's still holding .
