The trigger spring could be one of two types and I think it is the one that is held in with a small 4-40 screw that shows the threaded hole in the trigger housing. I had to make one from an old hack saw blade works fine. I thought I had a print of this one but can't find it right now, will look.
The other type is a bent piece of .020 music wire.
As to the safety spring, again their are two types, one for a three position and the other for a two position. Once you find out which one try Jerry Andrews 304-281-1740
