Upper Arm Assembly fell out of it's mounting

After I got the replacement parts I discovered how the upper arm retainer holds the upper spray arm in place. It was a simple pop out the old retainer and push the new retainer in place. All went well.

PS The delivery time was sooner then stated. The on-line delivery time for normal delivery was 3 to 5 days, but I received the parts the next day. I am very pleased with the ease of ordering and ease of installation. Parts Select did a great job.
