Registering a Warbird with the FAA (Experimental Operating Limitations)

It looks like I'm about to become the owner of a warbird which will
require setting up Experimental Operating Limitations with the FAA. I'm
planning on calling the FAA and the EAA on Monday, but is there anyone
out there who has gone through this before?

I have a copy of the letter the current owner has on file and I'm
assuming I need to develop a similar letter with my local FSDO, with a
map of my 300nm operating radius, along with the listing of planned
exhibition events.

I know what the final results of getting these operating limitations
set up looks like because I have the current ones. However, I'm a
little unclear on the process of how to get these set up in the first
place and on file officially.

Any insight would be appreciated.

Thanks,
Eric
