No, I don't, but basically you have to almost totally strip the frame to remove the trigger and drawbar. The trigger play spring is riveted to the draw bar and is not easy to get off. In your case, of course you can break the old one off if it is already broken. Before you do, study the way the old one is in as that spring is easy to get in wrong.
Not one of the S&W designers' better ideas and, IMHO, an afterthought (Hey, Charlie, can you stop the trigger from flopping around?).
(FWIW, it might be better to ship the gun to S&W or find a gunsmith familiar with it.)
