Frank, I have not seen this mentioned above but you might want to try this. Take the top cannon off of the frame. Push in on the sear bar. You should hear the click of the fireing pin being released and fireing. If not, pull the toggle back and try again. No click? It's not the sideplate that is the problem. Pushing in on the searbar SHOULD fire the weapon. If it does fire..the problem can be isolated to the trigger and sideplate. With a misnumbered sideplate..I suspect it already.
If the trigger pull is spongy you might also want to check on the spring behind the trigger. Some people lose this apon disasembly and replace it with a ball point pen spring making it mushy.
