Magento: How can I change the shipping method title at the checkout page?

Question

Basically what I'm trying to do is on the Checkout Page, I'm trying to change the USPS 'First-Class Mail Parcel' to 'First-Class Mail Parcel (3-5 Business Days)', 'Priority Mail' to 'Priority Mail (2-3 Business Days)' and 'Express Mail' to 'Express Mail (Next Business Day)'.

Already tried using the translate.csv solution suggested in the below link. For some reason, it only changes the UPS text, but leaves the USPS unchanged.

How to change "shipping information" label in magento while registration and checkout process

Also tried using Translate inline via the Admin Panel, but couldn't get it to work. Hated that function anyways. The book keeps moving whenever you move your mouse making it very difficult to click the box.

There has to be a way to change this...Any help would be appreciated. Been searching Google and the forums for a couple hours now for such a seemingly simple fix.
