Storm damage insurance horn replacement on a 66 C10?

[msg]

I need to find replacements for the insurance adjuster since my C10 had parts that were in a garage that got hit by a tornado and when it comes to the horns that need replacing I wasnt sure what to send as an estimate. I first went to LMC but they are out of stock without a price to submit. Mine were the original Delco Remy and one got crushed and the other was not found.
