Wasn't sure where to place this so we'll move it if it would be better placed in another sub-forum.
In my thread detailing upgrading E250's with 2008 and later front brakes I mention finding a few new take off parts from an eBay seller---this is that outfit's items for sale now currently available:

They're a good source and as you might expect their inventory changes almost daily. Easy to deal with, great service and FWIW I never had an issue buying from them. They seem knowledgeable about the E-Series along with other brands and vehicle types as well.
I hope some find this a useful resource!
