I WAS HAVING SUCH A HARD TIME FINDING THIS PART. Finally I found it through this company. Took 3 weeks to get it , however it was worth it. I check Home Depot , Lowes and other local plumping suppliers none had it. Found it on this Chicago Faucet shoppe.com Thanks Guys and gals.....

Part was on sale and my order was handled by a very courteous gentleman. Part arrived when promised and my toilet is now fixed. As the part was on sale I ordered a backup for a 2nd toilet. I would do business with this company again.
