@galo5150, Unfortunately, this housing is not available in the iFixit store, but there are loads of them available on eBay, if you search for “ipad 6 housing”
Don’t just pick the first result or the cheapest! Check the feedback of the sellers, both on item description match and their shipping & handling. Sometimes it’s far better to pay ~20% more for an item from a seller with much higher positive feedback and more sales, than to buy from some random seller because he/she was the cheapest.
PS! I also checked with ReplaceBase and InjuredGadgets (which are two I trust outside of iFixit), but neither has 6th gen housings in stock.
