Found The left side motor mount rubber for a ‘65 413.

I have the brackets so really only need the rubber as shown in these photos.

Summit Racing ANI-2227 and 2228 .I just bought a pair for a 63 Belvedere Big Block.

Yea, I’ve seen these but the one I am looking for has 2 studs on each side. Thanks for the lead!

I discovered Schumacher sell a close to original left side one with the brackets, but the rubber is a little different but more common I think it said. So that’s the direction I am headed.
