dont concentrate on the drip rails right now. If you are new to all of this, just dont jump in with grinders and cut off wheels a blazzin. That is a mod that is a lot harder and more time consuming than it looks. Dont worry we're here to help. just slow down a little. Do your other sheet metal first and get used to everything then takle your drip rails.
