Mike, it should be easy.
This bridge drops right on. to remove the old studs get a piece of round metal(a nail or small threaded rod)and cut it so it's to a little more than 1/4in.long-make sure it'll fit in the hole after you remove the screw. drop the cut nail or rod in the hole and screw the screw back into the hole... the stud will rise out of the hole and you can pop the new(gold one)right in,
for the tail piece make sure you measure post to post, then go shopping.
I've used these bridges on 2 Epi's(SG and Dot)with NO problems.
