Guess I need to go shopping. Springs are readily available, pawls not so much although Desert Ord can probably fix me up if I can't find them elsewhere. Just to clarify, the parts list in TM9-1005-224-29 doesn't show a "top cover pawl." Are you referring to the pawl in the feed tray or something else? I just happen to have a complete spare feed tray assy.
It is the little spring-loaded gizmo with fingers that grabs the belt and advances it.
They are pretty widely avail at the common places...
Here is a topcover feed pawl on GB so you know what you are looking for:
Aaron has them, too.
The other is the feed tray pawl that prevents belt from slipping backwards
also very common
