Yeah, I put in one of the resomax bridges on my epi lp. It's straightforward, though it might be a tighter fit it's easy enough to get in by hitting it down lightly with a rubber mallet or use the end of a screwdriver protecting the bridge with a cloth so you don't damage the finish.
Just make sure you get the right size, they supply both metric and imperial sizes depending on what type of guitar you've got. (eg - USA or Korean.)
If your getting the nut with it that might be a little more complicated, it's not that hard but if you fear damaging your instrument it's best to play it safe - if your in any doubt go to your local tech.
