My touchscreen no longer working due to crack screen.

Caveat here; I don't work for iFixit, just a volunteer moderator.

It doesn't look like the iFixit device page for your Asus sells anything other than the battery for your laptop. Although I can't fault you for wanting to buy an iFixit quality part, it looks like it's readily available on other sites like Amazon, ShopJimmy, and AliExpress among others. There are plenty of used screens being sold on eBay as well; that generally assures you're getting a factory part and frankly LCDs don't actually wear out, so that would be a good way to save a few bucks if that's an issue.

If you want an official iFixit answer, your best bet is to contact the iFixit Store personnel directly. This is the repair forum, and the Store folks don't generally hang out here looking for Store questions so I suggest emailing them at support@ifixit.com to get an answer.
