Mac Pro 2019 Rack Rail Kit replacement

This isnt a question but more of a helpful note. I purchased a second hand Mac Pro 2019 rack version and it didnt come with the rails. Speaking to apple support I was able to get a repair to get a replacement part for the left and right rail. Finding second hand rails is almost impossible as there was only 3 apple rail kits sold on ebay in the last 4 years, hopefully this helps someone. They quoted $220 USD for the left and right rails with inserts that attach to the chassis.
