I did the same thing with my SE custom not too long ago. Here is a copy of the post I made over at prsforums.com

Maybe this will help you out. I'm getting ready to cover the pickups on my 2012 SE Custom 24 because I hate the look of Zebras. I found some very nice, inexpensive covers online that are going to work perfectly. Here is the info.

I would suggest using a caliper to measure the distance between the centers of the outer 2 screws on your pickups. Mine are 49.2mm for the neck and 52mm on the bridge. I chose to go with the raw nickel covers as I plan on polishing and brushing them before installation. Getting the raw ones ensures that you won't have to worry about burning through any kind of plating.

They also offer covers with no holes or 2 rows of holes in nickel plate, chrome plate, and gold.
