I purchased one from: www.lmctruck.com

Here is the link: http://www.lmctruck.com/icatalog/cbe/0045.asp

It was a direct bolt-on, however I did have to jockey the rear bumper brackets a bit, but everything fit and worked as designed.

Here is a picture of the receiver hitch installed on my '66 Chevy C10 lwb fleetside truck. It is hard to see, but it tucks up nice to the factory chrome bumper.

I hope this helps.
