Here's my post (I realize I'm a day late...) but if you choose to finish the project by replacing the rest of your bunks @Bruce had a really good write up...
And mine are holding up well using Home Depot products.
My 2 cents...

I do not deal with lumbar a lot so I bought 2 x 6 treated wood but now that I've got here the tag says 2 x 6 treated but it's is actually .5 inch short on all sides is that because it's treated?

2x6 is the rough cut dimension. After planing it is 1 1/2 X 5 1/2.
