Another E-bay purchase a few years back was a NOS Horn relay that was supposed to be for 51 pass is a Delco Remy stamped 822. It is about 25% larger and the terminals are not all in a row there is one on each end and one square in the middle.
I looked through the books and found a Horn relay part number 1116775 it says its for 1934-51 chev but I'm not sure how to figure which Delco's will work from here?

The original seems to be a bit toasted and the contacts were fused/frozen together, and I did manage to separate them without too much damage????

Question will the nice clean, NOS 822 work as a replacement?

the mounting bracket holes line up but are not chromed, FYI
