edit: they're trying to sell you a drive/labor you can do yourself 😀
you're fine with just about any compatible CD/DVD-RW drive, the inside of the door is rounded out, so that the front drive bezel will roll right over the "hump".
if you're really worried about the old smaller drive bezel, then remove it, it's taped on with 2x sided tape, and gently remove the new bezel, you'll need to check your specific one (some move over, and then up, some move up and then over).
if you need any other help, PM me
