Greg,
Triggers for the Remington 788 can be made to work but IIRC the safety needs modification to fit in the stock. Brian Voelker can do a very nice trigger job on the 581s but he won't work on the older 581. Do a search on RFC in the Remington forum. His number has been posted there several times. 541S triggers work fine but they're difficult to find.
